Champion Specific Keybindings

Hello, i've made a thread before on this topic but I really want it to get implemented so I shall make another one.

As an old WoW player, I'm quite used to playing with keys other than QWER.

I use 1, 3 2, q, e, w, 4, r and more to play my champs, depending on which character feels better with what.

Would it be possible to make it so that the keys used are Champion specific, that way I don't have rebind my keys after every champ select depending on who i'm playing. :D
