Is there a way to make all of my HomePod minis play the same music simultaneously?

I have six HomePod Minis throughout my house. I want to be able to go from room to room and have them all playing the same music. I know that I can create a stereo pair, but not all of them. It seems that I might be able to airplay from my phone to them all (but I’m not sure). But I don’t want to do that unless I have to.

Is there a way to do it natively?
