Custom champ categories/groups for champ select?

I don't know about anyone else, but I find it bothersome to have to scroll through 100+ Champions took look for e.g. A mid laner to play. I feel like it looks nice how it is, but there should be options where we should be able to flip between categories made by the user. Just a thought, I havent heard anyone talk about it so maybe its just me. I just wanted to put it out there
