Schedule an announcement to play for specific days?

I have a time condition setup for each of my 8 locations which then goes to two different IVR’s depending on time of day. i.e. If the location is open or closed.

With the upcoming Christmas and New Year’s holidays I am trying to figure out how to play a specific message for each location for the days we are closed without having to manually go in and change the announcements for the IVR’s
