Is it possible for one or more TV's to audio output to the "Everywhere" group in Alexa?

I have four TV’s and I’d like sometimes for whatever is playing on one of them (rarely do I ever have more than one TV on at a time, if ever) usually the news, to play on the Everywhere Group so i can still hear it when I’m not in the same room as the TV or when I’m not in a room where the only two devices Alexa lets you output to when set up in Theatre mode.

So I’m thinking that HA might have a way to do this. One TV is a Roku by Sharpe, another is an Amazon FireTV and the other two are both Samsungs, in case that matters. The three that are not the Amazon FireTV, each have a 4K Fire Stick or a Fire Cube attached to them.
