The Message Scheduling features in the Tune platform, allow a specific message or set of messages (like an in-store overhead announcement such as an event or reminder) to be played in between songs (preset) or scheduled at a specific time of day.
You can create as many presets as you want, and then assign them to play at your locations. Schedule the messages into a group, set the frequency, and then turn it on at the location.
