Please add a way to add sets

As weird as it is, I have several cards that I cant either because a). the set doesnt exist yet or b). the set does exist, but you cant add a card. I've noticed this problem with 2022 Topps Match Attax 101 The Road To UEFA Nations League Finals and 2023 Panini Stars & Stripes USA. Other than this small thing this has definetely been the best app I've used for cards!
