Store Widget - Multiple Artists?

Hello all,

First off I love FAA, and have a premium account and use the store widget on my site and absolutely love it.

Now, I am starting a project that involves some other artists, and I've searched high and low: is there a way to make a store widget with multiple artists works displayed in the same "store"?
If this is possible, it would be an absolute lifesaver.

I've learned how to manipulate the store widget to display keywords, products, etc and that works great.

If it were possible to make the widget display all works on FAA, then a very specific keyword could be specified to tag all the artists' works together in one search result, that would be totally awesome.

I do know that separate artists' widgets could all coexist on separate pages of one site, and I think the shopping cart has persistence to "go" from one artists' shop to the next, but still I really want to have just one widget, and one store.

The only other alternative I see is to make an eCommerce store where customers shop, checkout, and pay, but then each artist will have to manually drop ship from FAA to the customer, also makes paying the artists a pain since that too will have to be accomplished manually, not nearly as elegant a solution as FAA's store widget.
