Provide possibility to modify volumne of fellow interpreters

Current state

As an interpreter I will usually work with at least one collegue (fellow interpreter). Currently, whenever I choose the same target language to speak to - I will always hear the original audio as well as the translator.

That becomes quite annoying if you always hear two audio signals at the same time.

Desired state

There should be a way to change the volume of my fellow interpreter and/or the floor audio.

It could be done using a cross-fader / knob or similar.
