Isolate one track from a monitorgroup

Hi! I have an IOS and an IOX which I use to record my band in a live setting. We are five musicians, so I have made an individual monitor mix for each, routed to different headphone-outputs. One of the tracks are holding a click for the drummer, and no-one else need to hear the click. So I have made a group for the drums (group 1) the click at group 2, and rest of the band are mainly routed to Main. However I can’t isolate the click in the Main mix. Any suggestions would be very helpful?
