V2CalendarPostItem - let us set categories

[michastrohmaier]

I created a leave request app for our Organisation.

creating an calendar event for the user works fine.

My Problem is as following:

we have additional tools which look for specific categories and filter views.

It would be really great if I was able to assign a categorie to the calendar event i creat.
