Volumn Fader Button in track header

It would be nice if there were possible to add a button to the track header, where you can press the mouse button and move mouse up/down to adjust volumn instead of selecting the track and then use the inspector to adjust volumn. Also selection sould not change when you use that “Volumn Button/Area” to adjust the volumn of a track.
This would be a way to quickly adjust volumns of track you are not working on without changing the selcted track and it would be much faster instead of selecting a track and then using one of its faders.
