Is it allowed/ advisable, to mark Christmas collections with different designs as a Cross-sell collection? For example, I have a few music designs, that are in their own cross-sell suites for each design. But the Christmas cards for those suites are actually a matching set. If they were together in a separate music- themed Christmas collection that was marked Cross-sell, even though they are different designs (and I'd have to mix and match other different designs to get enough required products), then the other cards of the set would show up underneath each product as "more styles for this product." Then maybe people could see the whole set and buy some of each design.
I'm not sure I'm even explaining this right- I hope somebody can understand what I'm talking about!
