Modifiable .ics files

It would be great if you could add the information within the .ics file that is sent after a booked appointment.

Currently, only the appointment name, time and date are stored there.

We would at least like to add the address and name of the company and the telephone number.

It would also be nice if the cancellation link could be stored there.

The same applies to the manually downloadable calendar entries for Google Calendar, Yahoo Calendar etc. after the appointment has been booked.
