Editing Automation Lane

Is there a way to grab the entire automation line in a lane and make a relative change? For example, reducing everything in the fader lane by some amount.

In Mixbus I know the answer is yes, can’t remember but pretty sure it got put in Ardour as well. Use the range tool to select a range of the automation track, then the draw tool to drag that range up and down IIRC.
