Wish Envelope Follower for Input 3 & 4?

[Chadwick]

I think I'm on my 3rd and final wish with the magic lantern haha.

Would this be possible? In the controllers menu it's only allowable on input 1 & 2.

It would be even better to be able to select left or right for each of the stereo inputs too as the Envelope source.
