Possibility to sync volume from other devices

I own a rose RS201 and a RA180 and I just noticed that in the rose connect app it is possible to connect the RA180 alongside the RS 201 and control the volume and some basic function.
But I notice it seem to be only possible from the app, and that it doesn’t seem to work with the RS201’s remote.
It would be so nice to have the possibility to have only one remote and make the devices able to communicate volume and power state.

Please note it is not a duplicate of RS130->Terminator Plus->RA180 Volume Control

I intentionally placed this as a feature request.

Currently, one remote control can adjust the volume of two devices separately.
Based on the photo you sent, it appears that the RA180 has been registered correctly.

What additional functions would you like to see added?
