Global Adjusting of Automation

[Sacalait]

I've been a long-time Sonar user and have been using CbB since Bandlab acquired it.  

If I create a project and use volume automation on each track, I know I can highlight all and move the automation by grabbing a line  in the track pane, hold the control key and move everything.  But it seems like globally raising or lowering the volume (in the track master pane on the left) on each track (CTRL_A then CTRL and grab the volume to adjust all tracks) DOESN'T adjust or move automation.  Am I doing something wrong?  Not designed to do this?  Every now and again I may want to ride a fader on just ONE instrument (not create volume automation for all tracks).  The frustration is if I want to globally lower all  volumes that ONE automation track doesn't get adjusted.  
 

Thanks.

Moving the volume fader wont override automation that already exists in the track since the envelopes control the fader.
What you are looking for is offset mode.
