Champion Sorting System Idea

Have you ever picked a champ that you didn't want because you couldn't find the one you feel like?

IT WOULD BE AMAZING if Riot added a champion sorting system where you can create different groups, name them, add champions to them, organize them. Imagine if you want to play support and scrolling down to your support group where you can see all the supports you have in whatever order you feel like.
