How do I create a location?
You can create locations by going to Trac Navigation > Search Glass > Center Profiles > [Your Profile] > Prefs > Scheduling > Appointment location choices. Add each location to a new line and save once you're done.
How do I add it as an option when searching for appointments?
In the same menu, scroll down the the bottom and check "Show location on search". You can also make this question required by typing "REQUIRED" in the text box.
How do I add it as an option in availability/appointment entry?
Scroll back up to the top, and check "Enter in avail" and/or "Enter in appt". You can also choose whether or not this field is required when booking an appointment with the "Required" box.
