The rule is simple to remember: if a patient agreed to an appointment, use the calendar
Before you ever drag a card to Consult Booked or Procedure Booked, ask: did I book an appointment in the RootLogic calendar for this? If yes, the card moves itself. If no, go to the contact record, open the Appointments tab, and book it first. The drag impulse is natural — but for these two columns, fight it every time.
