From what I can tell the voice remotes also run via the same communication method. Do you have a device that you are hooking them to via hdmi that maybe you can use arc (device control)? I have 3 remotes 2 of them pro remotes but I did notice you pair those to the specific TV. I'd say you probably either use arc or pair each pro remote to different tvs. They use same communication method but they are paired unlike the default remote.
