Configuring the task manager

I need help re-assigning the shortcuts for new entries in the task manager.

I’m working in Ubuntu Studio which comes with Ardour as the second entry, however my main DAW is Reaper. I’ve gotten Reaper into the Task Manager widget so that it appears at the top of my screen.

But I can’t reassign the second task manager entry from Ardour.

I would also like to have Kitty as meta+1 but can’t reassign that either. Help much appreciated.
