Quantity increments for a pool of products

[crc2004]

Any way to require that a pool of products be sold in quantity increments. We have 8 flavors of raw dog food and we only sell it by the case (12). How can I allow a customer to make a custom case choosing the flavors they want but limit the total quantity of all flavors to a multiple of 12? Anyone have a solution? Thanks

A quick way would be to have a product for the case and have 12 options, with each flavor. Customers can then choose the 12 flavores they want in the case.

We were interested in this as well, because will allow "mix & match".
Were the issue is is if they want more than one of the same flavor.
