Siri Command to Add Additional Airplay Speaker to Output?

[robgreene]

Is there a Siri command that lets you add an additional speaker to the current output?

Right now, I have a HomePod Pair as my Default Speakers.
I also have an Airplay Sub.

I would like to say something like "hey Siri, play this through Sub, too" and have Siri bring my sub back in to the audio mix, no button presses required.

I’ve used: “Hey Siri, also play in the [ROOM]”

Obviously ROOM is the location of the HomePod.

@kissfan, interesting thought - so separate the Sub to it's own room, then use your Siri command to add that room. Will give it a try this afternoon and report back!
