Option to change faders in mixer to effect other levels

In the mixer page, the main fader of each channel effects the output level of that channel, as you’d expect.
My suggestion is that you could change these faders to control other things, like maybe an FX send or Cue send.
It’s a bit easier to write using these faders rather than using automation lanes.

On some if not most hardware digital mixers, you press a button and the all the faders switch to FX sends etc.
Can be really useful to see everything feeding a effect or cue quickly.
