There are times when there is a need to switch a schedule slot to the other department. It is now no longer necessary to cancel and rebook all of the appointments. There is now a new setting in the user preferences to allow department edits on the schedule.  When this is turned on, a new button will appear on the schedule page.  

Clicking on the button will allow the appointment slots to be selected and a dropdown to select the new department.  

Clicking save will update the selected row to the new department.  Making the change to the department simple and easy.
