Correct me if I’m wrong, but when you say ‘the groups’, it sounds like you assume that you must use those groups for additional monitoring, but you can easily change those groups into extra mixes, just like mix 1-8. You can do this by going to ‘mixer configuration’ in the setup menu, and selection the number of aux mixes you want. 8 aux mixes means 4 groups, 10 aux mixes means 2 groups, etc.
