Turning down the volume on the hiding slice

Sometimes I have multiple slices set to use audio. If the slices are mostly quiet that works pretty well. BUT if several of the slices become busy at the same time it can be hard to hear any of them. And individually turning off each one can be tedious--especially tedious if some hold-out slice is hiding far to the or right on some radio panel to which you're currently paying little attention.

To resolve this, I'd like to propose a Ctrl + Right-Click action on the speaker icon of a slice, that turns on the audio of that slice (or leaves it alone if it's already on) AND turns OFF the audio of every other slice on every other panel. This would occasionally save me a good deal of time and a generous helping of frustration, as well.
