SMS 12 allows for use of an "envelope" to pan the volume of individual audio tracks in a 5-channel DD 5.1 project. However, is there a way to pan the volume for all tracks simultaneously? Otherwise, there appears to be a nasty chore of setting up an envelope and control points for each individual track, and then have to synchronize them: a nuisance to do once, an ache in the head and bowel to do often. Most audio fading or ducking I'll want to do to all 5-tracks in conjunction, as I reduce or raise the native audio for the sake of a voice-over or some other effect.

Thanks for any suggestions or guidance.
