Specifying which Homepod Mini Plays Music

We have a household with two paired HomePod Minis used for audio output from an Apple TV. This is in the living room, which is adjacent to our kitchen. We have another HomePod Mini in the kitchen since, due to the layout of the house, it's impossible to hear the living room speakers while actively working in the kitchen.

Roughly 75% of the time, when I'm standing in the kitchen, approximately 5 feet from the kitchen HomePod Mini, and ask Siri to play X, Y, Z music, the living room pair starts to play. While I'm ~5 feet from the kitchen speaker at this point, I'm ~15 feet from the living room pair, including half a wall and a short hallway between us. If I stop the living room speakers and try the command again, the same thing happens.

I know it's a first-world, small potatoes thing, but it is so incredibly frustrating to, say, have soapy hands from washing the dishes and need to dry them off, go find my phone, pull up what I want to hear, play it, then specify the kitchen speaker.

I've tried tons of ways to orally specify which speaker I'd like the music to play on, including, "Siri, play X, Y, Z music on [Name of Kitchen HomePod Mini]," but it yields the same results; the living room speakers play instead.

Is there no way to specify, via voice command, which speaker you'd like to use?
