This would allow us to use multiple copies of the same things, like furnishings (such as the Dragon's Treasure Trove to make a larger treasure pile), pets/mounts (like farm or forest animals if it makes more sense for them to look the same), and Houseguests (if we wanted the same NPC/Assistant to "teleport" or be in multiple locations simultaneously).

This change would be significant for the Housing feature because it would open up new ways to use our Collectibles.
