I'm wondering if it is possible to create a subcategory within one of the wishlist categories that has already been made?
like for example category Cash Shop - subcategory stickers or wearable items that way I can break down the categories I have into possibly priority too like what items I want the most or which can wait till I can put it into an outfit :)
Nope, no subcategories! Most people looking to do something like this just name categories accordingly - "Most Wanted Wearables," "Low Priority Wearables," etc.
