I will try to explain what I am looking for.
I use Roon in this way:
Roon endpoint > iPhone 8 Plus > Chord Mojo
So the zone is iPhone 8 Plus with its configuration (fixed volume, DoP, etc.).
Sometimes I have the same zone (iPhone) without the Mojo but with my AirPods.
In such occasion I have to change the settings of the zone because it’s configured with the Mojo (fixed volume, etc.).
So, what I need is to duplicate a zone so I will have:
iPhone 8 Plus with Chord Mojo (with its own configuration)
iPhone 8 Plus with AirPods (with its own configuration)
Is that possible?
