Configure RZ30

Can I config RZ30 this way:
When I don't play music in Zone2/3, then I can get 5.2.4 or 7.2.2 in main zone (Zone2/3 should have no sound)
If I need to play music in Zone2 or Zone 3 (not both), then I can still get 5.2.2 in main zone, and I can switch on/off main and zone2/3 independently.
I thought a lot but couldn't figure out a way of connection.
