Is there a way to create a kit that contains a user-specified quantity per product that is added? For instance, my kit can contain six items selected from products a, b, c. One customer would like to be able to select 1 of a, 2 of b, and 3 of c, and another might want to select 5 of a and 1 of b and 0 of c. Is this doable?

Thanks,
Sue
