Favorite Champions Tab in champion select

When you're in champion select, there's these icons that allow you to filter the Assassins, Tanks, Supports, etc.

I feel like there should be a thing where you can star or favorite the champions you like playing, and it will create a tab for you in champion select. You favorite the champions you like, then in champion select, you can click the tab to show the champions that you fav'd. This makes it easier to access the champions that you play.

I mean sure, you could just remember the champions that you play but, personally if this would be in the game, I'd find it a lot easier to pick a champion
