Oppo 203 network standby / visibility in Roon Controller

Hi - I’m using an Oppo 203 as an endpoint in my home cinema system and I would very much like to be able to start it playing from the Roon Controller app without having to turn on the system first. If Roon can turn on the Oppo then I can use its 12v trigger to turn on the amp…

I’ve set it in network standby and had a thorough look for any other relevant settings, it will not appear as an available ‘zone’ in the Controller unless and until it’s separately switched on.

Anyone else encountered this and figured out how to work around? FYI it can be turned on over the network via its own controller app.

Thanks!
