In a couple of words, describe the feature you'd like to see:
I'm sure that like myself, many others use DisplayShops along with region renting plugins like AreaShop. When a player's shop is unrented and a new player rents it, the old owner's DisplayShops are still there, and an admin needs to manually remove the shops or set the owner to the new player. I'm requesting a command to set the owner of all Display Shops in the given WorldGuard region to the given player. This could be used with AreaShop's rental commands to automatically give the shops to the new owner.
