Appointment reminders should go to the assigned contact of the ticket.
I created an appointment from inside a ticket, and the confirmation email went as expected to the ticket's assigned contact, but the problem is that the appointment reminders went to the primary contact, who rang me to ask what it was all about.
Unless you are dealing with customers that have only one contact, the primary one, this is a PITA to have to remember to turn off appointment reminders every time you create an appointment with a secondary contact.
Is there any way to set the reminders to go where they should, ie the person (contact) who I made the appointment with?

This is an absolute must-have feature. Sometimes you are dealing with a department manager and need to make appointments with them specifically.
