Mute/unmute AOL?

First of all: thanks for your great work on this product. It’s a fantastic looper, thanks to your willingness to listen to us users - and the ability to make the nescessary improvements.
So: Will we be able to mute/unmute across a transition? This thread seems to also touch upon this issue.
I use the Midi Maestro, but fail to see any commands to mute/unmute tracks in a different part than the one I’m in.
So what I need is the ability to “mute/unmute track x in part x”.
