Key Binding Setup Improvements

When I play league I play different champions like Nami, Kayle, Lulu that for me require to have certain spells set to self cast + quick cast or turning quick cast off altogether. The next game when I play a champ like Rumble I forget to change my key bindings until I mess up my first ult in the game.

The main point is that I would like for there to be an option similar to item sets where you can make a set of key bindings and label them, so that when in champ select or at the start of the game you can easily change to your preferred settings without losing a minute or two setting them up.

If this goes through Riot can you give us the option to have at least 4 or more sets? I for one will be needing more than just 2 different key binding sets.
