Seperate settings for every Champion

My suggestion for the game is, to make it possible to change settings for specific champions. Like you play the champion and do the settings, and if you don't tick the box, it is only getting changed for this single champion. Or you can even make a menu to just choose the champion. In the end you can just use Overwatch as an example, since they've already put in this feature since release. In my opinion it is a necessary feature which can prevent a lot of trouble ingame. As an example there are a lot of players who just change the E from Quickcast to Normalcast when they play Veigar for instance or the R when they play Rumble. I can even count myself as an example since I play Shaco with Normalcast and I have a lot of trouble with first thinking about changing everything to Normalcast and then also make the R Quickcast since Riot changed the R so you can aim where your clone is.
