Every bundle of 3, get different price

Hi, thanks for a great plugin.

Maybe I have a brain freeze, but is it possible to get a different price for every bundle of 3 you buy? Example:

Hoodie (Variable product, available in S, M and L)
Regular price $10 each, every 3-bundled price $9 each.

Cart examples:

3 items of same product
————————-
Hoodie size M qty – 2
Hoodie size L qty – 1
————————-
Total $27 ($9 + $9 + $9)
————————-

5 items of same product
————————-
Hoodie size M qty – 2
Hoodie size L qty – 3
————————-
Total $47 ($9 + $9 + $9 + $10 + $10)
————————-

6 items of same product
————————-
Hoodie size S qty – 1
Hoodie size M qty – 2
Hoodie size L qty – 3
————————-
Total $54 ($9 + $9 + $9 + $9 + $9 + $9)
————————-

8 items of same product
————————-
Hoodie size S qty – 2
Hoodie size M qty – 2
Hoodie size L qty – 4
————————-
Total $74 ($9 + $9 + $9 + $9 + $9 + $9 + $10 + $10)
————————-

..and so on. Is this possible without adding hundreds of ranges? If so, do you have an example of this?

Thanks again!
