Champion Selection Groups

Have you ever been in a Champ select thinking, hmm, who should I play? Lets say you get jungle. you're scrolling through all your champs and only see a few. The timer is going down you only have a few seconds to select you pick the first champ you see or the first champ that comes to mind. Maybe you're not happy with what you picked but proceed to play anyway. My point here is in champ select they should make an option where you can put your champions in to groups. For example mine would look like: Mid: etc... and Top: etc.. So when you are in champ select and you call the positions you want or get the position through draft order when its your turn to pick you select the group you made and all the champs are there that you put in there so you don't have to look through all your champs.
