Champion Organization

I was looking through my list of champions recently (not complete, but working my way there). Then I wondered what if the champ list could be organized in such a way that people don't always need to rely on an alphabetical order of champions, role each champion envisions, and/or champion availability. I was thinking that each summoner can control how (s)he organizes the champion into groups according to how the summoner wants. For example, if a summoner needs a mid champ during gameplay, that summoner can go to his/her "mid champs" group and select from that summoner's grouped-up list of champs. Another example: the team needs a tank but several positions need to be occupied; the summoner can choose from a "tanks" group. Of course, the summoner would need to organize their champs according to their own system, making the champ-summoner system more intertwined. Also, I believe an addition of summoner-controlled champ organization would add a complexity to gameplay of individual champions as the game continually transforms itself. It could also make choosing champions easier during gameplay. All in all, some sort of summoner-controlled champ organization could really add to the intimacy between the champs and the summoners. Any thoughts fellow summoners?
