[Feature Request] Ducking Interview Audio: Duck against "Primary Person" v "Secondary Person" track

Description:
We can set Audio Types, so a Dialogue track gets prominence & other Audio Types (Music, Ambiance, SFX) can be ducked against the Dialogue.

It'd be helpful if there was a way to establish dominance/distinction for Person A's Dialogue v Person B (or Person C, for that matter).

So if PersonA is talking at the same time as PersonB, then PersonB's audio gets ducked/lowered; but if PersonA isn't talking but PersonB is - then PersonA's Dialogue gets ducked in the absence of PersonB's Audio.

Either as a "Priority Dialogue" selector, and/or a checkbox to generate "inverted" ducking keyframes.

Would be helpful for interviews where there's one person talking at a time. I have a monthly show & this Feature would definitely speed up the process!
