This would allow other locations to call each other to shunt clients to alternate locations, give information to clients saying "we're unfortunately out of appointments today, but location X has a 5:30pm available and I can connect you to that location if you'd like to set up an appointment with their concierge." Also useful to create inter-salon competition and schedule envy/understanding.

I would love it if I could say to my managers, please look at the holiday hours for location X, and duplicate them for the month of december, without them having the same management level access at multiple locations.
