Commerce - Display one package in multiple categories

[IPCommerceFan]

Idea time!

Wouldn't it be great if a Commerce Package could exist in more than one Package Group?

In database speak, have a packages' p_group be an array, instead of a constant.  Like this:  p_group='{"1","2"}', and in the ACP, call it "Groups" instead of "Group", and it be a multi-select instead of a single select.

This way, you could have a store where products that pertain to more than one package group can be listed in each group without having to be separate, distinct, listings of the same product.  It'd be better for sales tracking and SEO this way too.

If a package absolutely must belong to only a single group, then perhaps some sort of functionality to "also display in" would be suitable?

Thanks!
