Allow office hours, provider hours, and time blocks to be set up with multipe start and end dates for varying schedules throughout the year. Need ability to have different office and provider hours during different times of the year without changing the whole year or having to manually edit the office schedule for each day. Set hours by date range or day in range. Set time blocks to start as of a future date. Allow to close the office for a date range rather than selecting each day individually. Or specific days in a date range. More flexibility in the schedule so they can set up a provider to work every third Wednesday, every other Monday, etc.
