This function is identical for both Single and Multi-column appointment books.
EXACT caters for booking more than one appointment in the same time-slot. These double booked times are clearly identified with the use of colour in the ‘View Week’ and ‘View Day’ area.
Booking an appointment during a Block is also considered to be double-booking a provider’s time, e.g. booking an appointment during a provider’s lunch break.
As the required time slot already has an appointment, double-clicking on the required time will display the first appointment and selecting another patient can very easily overwrite the existing appointment. Therefore to add another appointment at the same time it is recommended that the clipboard be used.
