Virtual Zones or Zone grouping

Hello, 

FIRST POST :)

I have the A.6X and LOVE it. I would like to request you add a virtual zone/speaker that allows me to do the following without having to rely on a 3rd party home controller (i.e. google play):

1. Group multiple zones together to appear as a single AirPlay speaker

2. Allow me to pre-set the volumes in order to have pre-balanced audio volumes  across my entire installation. 

I have 5 zones active and while I can set the default volume per speaker I cannot keep the proportional volumes across zones in sync this way. 

For example  - with 4 of my zones assigned to a virtual zone called “BackYard”, my pool, patio, deck and bbq (all in the backyard) are easy to connect to and volume equalized. 

Fingers crossed!
