Import ics file

It is rather rare, but sometimes I receive an ics file attached to an email, with the full event details (e.g., a doctor's appointment, with location details). I can import that in Google Calendar on the web, but I cannot find where to do that in Morgen.

Obviously, one should be able to select an ics file on their computer, then select the appropriate calendar to which the event(s) from the file should be added.
