Choosing champions in championselect...

Hello, I came to this thought by not having enough time to choose a champion to play. The reason for it is because having too many champions.. So its hard to find the right champ in time. So the idea is maybe making preferable champion for the lane you are playing? For example, when you are playing top and you have to find all the top champs, then press some kind of a button for top ( like there are for assasins and tanks etc ) and you get all the top lane champions. I know a lot of people have the same problem of having too many champs and cant find the right one in time, specially when you are first pick.
