Orbit Voice Groups for Multi room music

All Amazon speaker enabled devices can connect with the Alexa app in groups... that is all devices except for the Orbi Voice. This is essential in our home because we make family broadcasts/announcements ("dinner!) using speakers in our home. We just welcomed a new Orbi Voice to our home and were so disappointed to learn it did not serve the very function we bought it for in our daughters room. A quick Google search showed we were not alone. Advertised as being Alexa enabled is not really accurate and is making us rethink this purchase.
