How to add multiple appointments from my app to the Native Calendar control windows 8.1?

Question

Hello All,

I have the following scenario I need my app to be able to add multiple appointments to the Native Calendar  control

without bothering the user every time when new appointment is come.

I found that AppointmentManager Class accept only one Appointment not List<Appointment> so is there a way to add multiple appointments to the calendar without asking everytime for permission?

Thanks.
