Reply To: Event before import/export

OK, now, the scheduler has a new BeforeAppointmentSave event.
I tried a lot, but it is never triggered.
If I put an ics-file by drag & drop in the scheduler, then the appointment is not saved so I think, we need here an import event.
Also the BeforeAppointmentCreate even is not triggerd in this case.
So I don’t know when the user has imported an appointment.
