champion specific key bindings

I have mentioned this topic in the past, but with the new client out and being constantly worked on i'm hoping it can gain some more traction this time around.

Many champions have specific key bindings that can hugely benefit a player for that one champion, but are useless and even harmful when still applied to others. from here on out I will be referencing one in particular, . but Many others do exist, I think of ult and E etc... cases where the usual quick cast just isn't ideal for anyone who isn't an absolute god with those champions and that know how to place those abilities well. when I play , I like having cast on release on, which makes q much easier to control, and the really annoying thing to swap back and forth is her E, which I think is extremely important to have on self cast unless targeting another champion, so that you never have to move your mouse over yourself for a shield, you can just panic press E and get a shield.

with the pre-minion time still being an important tactical time of the game, with possible invades happening and generally standing around as a human ward, there just isn't enough time to worry about swapping to these settings every time I want to play one of these champions that require special bindings, and then swapping back to normal bindings the next game if i'm playing a different champion. so now that its possible to edit your settings from the client, would it be so hard to implement an item set Esq system where you can set and save certain bindings to a particular champion?

Tl-DR: Champions use different key bindings, and we should be allowed to save them per champion.
