Optiopn to let Trim automation affect the whole track rather than after the cursor

Currently, the trim acts as another layer of automation and affects the automation after the current position of the cursor.

I would like to make subtle changes to the entire volume automation using the faders in the mixer.

Please add an option to let trim affect the whole track.

A dedicated Trim/Read mode would be great! Reaper does this quite well. All automation runs in the background while the faders are free for subtle overall changes.
