Swap "mute" and "solo" states in the mixer window

Practically, muting some tracks and/or "soloing" all the others have exactly the same effect.

But sometimes, you start by "soloing" one track, then a second, a third, etc. and you reach a state where it would simple to invert the situation so that all soloed tracks would become un-soloed and all un-soloed would become muted... (and vice versa).

Hence, a sort of "Swap" button would be highly appreciated!

Thanks in advance.
