For MIDI, it should be possible to some extent.  For audio, no.  This is a 
piece of functionality that would be very useful, and we've been talking 
about it for years, but talk is cheap, and there is neither code nor the will 
to get it written.  This would be a great pet project for someone with both 
coding ability and a personal stake in the issue.

It shouldn't be that difficult to do with the MIDI volume control.  You can 
use a control ruler to insert volume control events into the necessary tracks 
at the right places.  While this is not exactly a quick and easy solution, 
it's probably still less tedious than manipulating event velocities.

Assuming the virtual synths pay attention to the volume controller, actually.  
I'm not sure how well that might work.
