There's a new Service Providers/Schedules setting to let you link a schedule to itself across locations. This means a service provider can have the same work hours (adjusted for time zones) at several locations and not get double-booked.
For example, a business that schedules phone meetings with clients across the U.S. can set up one schedule with four locations one for each of the main timezones. Clients will choose their region of the country and then select an appointment time in their local time. By linking the schedule to itself across the four locations, double-booking a time slot is avoided.
