Champion categories

Hello! one idea I had was creating something similar to item sets for champion select. As of right now the categories for champion select are things like "Mage" and "Assassin" and etc. So my idea is to be able to create your own categories, so for example lets say we need some more ap on the team and im going jungle I could just type in "AP jungle" and a list of champions would pop up that fit the jungle role and are AP. thanks for reading my idea!
