Ability to sort champions?

With the addition of new "tabs" of champions (tanks, assassins, marksman, ETC) Couldnt we make a custom list of some sorts? There's so many champions to sort through, but imagine a custom build system like this, kind of like item sets. (Normal tabs) Fighters Tanks Mages Assassins Marksman Support

(Custom tabs) Top laners Mid laners

Idk, just a suggestion because I dont like the class sorting by itself.
