Changing automated volume level

[Mike Borok]

When viewing a track with automation in Volume mode, I know that you can use the trim tool at the end of the track to raise or lower the volume level of the entire track, preserving the relative levels of the existing automated volume moves.

Is there a way to do this simultaneously for multiple tracks? e.g. suppose there are three backing vocal tracks and I've automated all of them to balance in the various sections of the songs and to balance with the lead vocal, but then decide that the level of the lead vocal is too low so I increase that. Then I'd need to increase the levels of all three backing tracks as well. It is very finicky to get exact number of dB change by mouse drag. Then multiply this issue by many more tracks.

I just tried creating a group for the tracks and found that the end trim DID move all of the volume automations together, so that's good. Now...is there a way to type in a change value, rather than mouse drag?
