Automation Of Post Volume

Not possible to automate the Post Volume faders?
I dont want to attach a MIDI-knob to it. i wanna use the mouse or the Automation graph.
just cant find a way to do it…

Since the reverb or delay effects hang after playing, i want remove all noise in the song by lowering the volume for two specific tracks.

it’s in the TrackVolPan, there’s no option for Post Volume. ??

ok. Maybe i can use the Gainer for this instead anyway.
