I’m not sure if this is the right place to post this.
I don’t know if there is already, but… In the Locker I think there should be the ability to select Outfit/Back Bling and Pickaxe that are of the same bundle purchased. It takes time to browse through everything bought item and match them.
On another note, wouldn’t it be nice if there were a Locker Room where anyone could browse through all cosmetics? Not a menu, but a whole dedicated Room.
