Pre and post fader aux sends

Question

We keep running into issues in our signal chain design with the fact that the aux sends are all post fader, this means it's not possible to dynamically send to aux buses but then kill the direct signal feed (unless you forward that to some dummy bus which we then set to clear the output of via DSPs writing zeros).

It would be useful to be able to select if the sends are pre or post fader.

It would be super useful to be able to dictate where they are relative to the DSP chain too (i.e. apply 2 DSPs, aux sends, apply next 2 DSPs, fader), etc.
