It would be very handy to be able to add 2 patients to one appointment slot when you only need to see a patient for 5 mins instead of the full appointment time. I realize that you could add a group appointment to do this but the names do not show up on the appointment book and to do this you need to delete the original book and change the time slot to a group booking a rebook both patients in. The other option is to change the template for the amount of time allocated to each appointment of the clinic eg 30mins to 15 mins but in 98% of case I need the 30 mins - never mind the fact that I cant simply change the template of our appointment book with out making a huge mess. If there was an option that you could added an extra appointment into a previously allocated time slot - this could shown up by a diagonal or half way separation of the appointment slot so that it is obvious 2 people are booked in to a single time slot? Of course this would only be available to people with full access to the appointment book?? It is to allow more flexibility for the practitioner to "squeeze" patient in if necessary.
