Hotkeys - Custom Cast Sets

Hello guys, I have a suggestion to Riot Games team. Since I started play League of Legends I use different types of cast in different champs. For example in - R, - E, - E and - Q I use normal cast and in - R, - R and - R I use quick cast. In my last game I messed up the nami Q that was going to give some advantage to my team, that happens because I usually use her Q in normal cast, and in last game I played with Lulu where I use my Q in quick cast. That's happens to me a lot and I need to change that every game, and I think since League of Legends as a Custom Items Sets, why doesn't add a Custom Cast Sets. What do you guys think about it? Sorry for my bad english. [vlad-salute]
