Yes, I used a group when I setup a page to control the looper on my Timeline delay pedal. The Record, Play, and Stop functions on the Timeline are mutually exclusive. By putting three buttons in a group, only one of the buttons in the group lights up. For example if the Play button is the active button, when I press Record, the record button will become active and lit and the Play button will become inactive (not lit up). I hope that makes sense.
