Editing Temple Baptism Appointments

[ekohlhase]

I made an appt for proxy temple baptisms. I've tried to edit the appointment to add more people than I said when I originally made it, but can't seem to figure it out. Can you "edit" a reserved appointment to edit the # of people coming but keep the same date/time? It seems like it wants me to find another time if I edit the number of people going.
