Note Off entire track with one command/script

I like to do a lot of “trading fours” style tracks where I will remove a part for a bar or two and then bring it back in. The way I am currently doing this in Renoise is by deleting the track for that pattern and putting in note offs in the first position of each column. I was wondering if there’s an easier way to go about that, like a keycommand or a script or some other automated action.

Have you tried Ctrl /Cmd+ capslock?
