Recognize Broadlink as an Airplay Speaker
I’d like to control the volume and power of an amplifier that can only be controlled via IR within the AirPlay menu in control center.

I have many AirPlay 2 enabled speakers in my home (HomePods, Sonos, etc.) which I control via the Airplay menu on my Apple devices. I play music through my iPhone, for example, then select speakers I want to use. I also control volume of these speakers via the Airplay menu.

I have a Sonos Port connected to the Amp in question, which feeds digital audio data to the amp. I can control the volume of the digital audio data via AirPlay, but I’d prefer to have that data flow at a fixed volume.

I’d like to be able to select my Broadlink within the Airplay menu, which would then power on the amp, as well as have the volume slider send volume commands via IR. Deselecting it would then power off the amp. This would be in addition to selecting the Sonos Port for the audio data. Is this possible?
