[Plugin: TheCartPress eCommerce Shopping Cart] Customizable product package orders

I’m trying to set up a shop that allows for customers to mix and match to purchase different product styles within preset quantities.

For instance, a 10-item package for $15 allows selection of any number of product styles A-E (up to 10). Customer can choose how many of each style he wants: 2 A, 3 B, 1 D, and 4 E for a total of 10.

A 15-item package for $20 allows customer to mix and match the same styles for a total of 15, and so on.

Products are not sold individually.

Is this possible to set up in TheCartPress? Any ideas how?
