When booking an appointment, there is the option to add a note, is it worth adding there which surgery you will be seeing the patient in?
This is will then display on any printed day list for you to see and refer to, and reception simply need to hover over the appointment to know where the patient will be seen.
To add a note for an appointment already booked, double click the appointment in the diary, on the right side of the appointment details type in the note section. click OK.
Please let me know if that is helpful.
