Binding a textblok hide/unhide action


I’m using song notes for an overview of sounds (parts) that are currently active in the song; one textblock per sound. Using the songpart I can hide/unhide individual text blocks to see which combination is active.
I additionally would like to hide/unhide these text blocks, based on the binding. This way a ‘select’ button on my hardware control surface is reflected in the songnotes list.

Is this possible? Couldn’t find it in binding targets.
