This is just a suggestion for the furniture crown store. This wouldn't take any new assets and would be relatively easy to do.
I like to have my homes looked lived into and I frequently group up various pottery such as urns, vases, jars, & pots. It would be nice to see duos of pottery or trios of pottery to place as one item so that they don't take up too much of our limited item counts.
I'm sure this could be applied in other ways such as various plates already having food & silverware.
PS if ZOS likes this idea, feel free to send my a sampling of the grouped pottery!
