Something simple - let 1♠ promise only 4 (could be minor canape), and use 2♦ as an asking bid for a 4cM after 1♣-1♦-2♣ similar to after a precision 2♣ opener.
If you want something more complicated, see my previous discussion, and in particular this is my "solution" to the general problem of poor constructive bidding after starting 1♣-1♦.

Probably it makes sense to rebid 1NT sometimes with 2-4-5-2, but we never thought about it

1♣ - 1♦ -
2♣ -
2♦: Asking bid, allows opener to show a 4 card major.
2NT: Diamonds.
1♣ - 1♦ -
2♦ -
2♥: Asking bid, allows opener to show a 4 card major (2NT shows 4 hearts, opener can't be balanced).
2NT: Hearts.
Edit: Sorry didn't see gwnn posted exactly the same thing. Just to make an original contribution, here is what I saw in TOSR for opener's rebids over 1♦. It's from memory so I hope I'm not messing it up, but it's very much like Woolsey over 1NT.
1♥: 20+
1♠: 6+ minor or 4 major 5+ minor
1NT: 17-19 balanced
2♣: 4+/4+ 9+ total majors
2♦: 6+ major
2♥: 5 hearts 4+ minor
2♠: 5 spades 4+ minor
2NT: 5+/5+ minors.

Over this you can play 1N as a retreat for a poor hand without a fit and then use 2♣/2♦ to show varying degrees of support / strength. Alternatively, you simply raise to 2M with 3+ card support and a relatively decent hand.

jdonn is right, but I think TOSR's 1S rebid can be 5m4m as well.
1C-1D, 1S-1N
2C-5 clubs and side suit
2D-5 diamonds and side suit
2H-4H and 6m (unspecified)
2S-4S and 6m (unspecified)
I can't remember the difference between
1C-1D, 1S-1N, 3m and
1C-1D, 3m

1C-1D, 1H
1S-0-7 with 4+ spades and 0-3 hearts
1N-0-4 with 0-3 spades and 0-3 hearts
2C-6-7 with 0-2 hearts
.....2D-relay
..........2H-2-fit
2D-6-7 with 3+ hearts
..........2H-sign off
...............2S-4S/3H
2H-0-4 with 4 hearts
2S-6-7 with 5 spades and 3 hearts
2N-?
3m-6-7 with 6m and 3 hearts
1C-1D, 1S is similar, but I can't remember what is. I think, however, that
1C-1D, 1S-2C, 2D-2H is natural
So I'm leaning toward 1C-1D, 1S-2H showing 6-7 with 3S/5H

In addition to what others said, counting 225m4 as balanced when in your nt range means the only hands you are worried about are 1345 and 4450. Over 2m, if responder is non-terrible they can also just bid natural to look for fits. I haven't found much problem with this to date. The major fits sometimes are buried when the hands are both terrible (in context), but even then the opponents sometimes balance and let you find a better fit.

All of these suggestions are very helpful. I like this idea in particular because the agreements can be on after interference and we often get interference when responder is weak. So, for example, we could use this structure after 1♣-pass-1♦-1♠.

I suggest bidding out your shape as game is usually remote --find best partial fit. Thus 2m, not 1M on 4-suit. Let partner suggest his suit if he has one; max negative if that.

Precision has an unhealthy fixation wiuth 5-card majors. 5 to open 1♥, respond 1♥ to 1♣, rebid 1♥.
I think they should all be 4-carders but you'd be looking for a new name.
If 1♥ & 1♠ rebids could be canapé, you take strain off 2♣ & 2♦, which is good. Still, you need to be prepared to play a few 4-3 major and minor fits.
After
1♣ 1♦
1♠ 2♠
you need some adjustments. Since this could be a 4-3 fit, opener needs 5 for a normal game try. With just 4, opener can rebid 3♣ & 3♦ as non-forcing canapé tries. 3♥ could be a help-suit trial, 2NT can be something fancy, such as start of a short-suit try.
The problems come when responder has a bit too much for a single raise but only 3 trumps. Say:
♠K76 ♥T4 ♦A7654 ♣872
If 1♠ showed 5, you would bid 3♠ or equivalent. That's dubious opposite a possible 4-carder. Either make a heavy single raise or have a Drury style 2♣ bid to show this.
The other issue is opener's 2♣ & 2♦ rebids being 5-4 either way. That makes a traditional forcing notrump less workable and jeopardises the 5-2 major fit. For instance
1♣ 1♦
1♠ 1NT
2♦ ?
♠J6 ♥A753 ♦J43 ♣T654
responder should pass now in the possible 4-3. Bididng 2♠ risks a silly 4-2.
None of this bothers me in the slightest.

Doesn't matter Bob. Only for game MAJORs are superior. 5-3 and even 5-2 minors will better for a partscore than looking at a higher level for 4-4 majors.
This means if you introduce your second suit you will be looking for game.

Cheapest rebid by responder can be 0-4 hcp and all others 5-7.
Berkowitz and Cohen have played 2♣ (0-2M) and 2♦ (3M) with 5-7 hcp. There are other artificial follow-ons for responder: 1NT comes to mind from Toad Club that is 5+ cards in a black suit and 2♣ = 5-7 hcp, no 5-card suit (balanced). 2♠ = any 4441 & 5-7 hcp.
Also, some prefer 1♣ - 1♦ - 1♥ to be 19+ and balanced, or 4+♥ and 2-suited. Precision Today, 2002.
Preference somewhat depends on style and Pairs or Teams.

Based on memory and adjusting for the Precision range of 16+ unbalanced and 17+ balanced:
1H = Relay with 19+. All others are 16-18 unless noted otherwise
1S = 4+ spades, unbalanced. May have longer minor.
1N = 17-19 balanced
2C = 4+ hearts in a 2- or 3-suited hand.
2D = 3 cards in one major, 0-1 in the other.
2H = 1-suited in hearts
2S = Fewer than 3 cards in both majors, clubs are longer than or as long as diamonds
2N = Fewer than 3 cards in both majors
3C = 6+ clubs, 3-3 in majors
3D = 6+ diamonds, 3-3 in majors
I don't remember whether this was part of system:
3H = 5+/5+ in majors, strongly invitational. Perhaps AKxxx/AKQxx/xx/x
3S = 5+/5+ in majors, GF. Perhaps AKxxx/AKQxxx/x/x
You won't miss your 4-4 major fits unless the 1C opener rebids 1NT. And you will find many 5-3 major fits as well.

1♠ ART one round forcing (20+ unbal or 25+ bal).
1NT 17-19(20)
2♣ 5+ card major
2♦ 4+4+ majors or 23-24 bal
2M 4M5+m
2NT (20)21-22
3m 6+m
continues
1♣-1♥;1♠
1NT I have real junk. then 2♣ real FG hand asking responder to show the distribution.
2♣ bal or ♣ FG
2x 5(4)+ FG
1♣-1♥;2♣
2♦ relay, then 2M 5+ may have 4m, 2NT 5+♥5+m, 3m 5+♠5+m
2M/3m nat NF no interest in the major
1♣-1♥;2♦
2M preference
2NT/3♣ transfers
3♦/ ♥ transfers to 4 card major (inv vs majors)
1♣-1♥;2M
2NT asking for minor
others nat nf
This did give very good tool choose correct partial and bid thin games with good fit.
edit: 2NT opening was minors either weak or strong (forcing to 3NT/4m) and 1♦ might be opened heavy with 5+5+ minors so 1♣ denied 5+5+ minors.
