For example: on Steam there is no way to wishlist "Shadow of War Definitive Edition" so I have wishlisted standard "Shadow of War". On GG.deals I manually wishlisted "Definitive Edition" and unchecked/removed "standard edition" but everytime I sync with Steam - standard versions are comming back.
It would be nice to be able to hide items on wishlist, so they will be imported but not displayed on wishlist.
