appts+ add subject to google calendar add email

Hi
When an appointment is made, I receive two emails - one is the copy of the confirmation email and the second is the calendar insert from developer.gserviceaccount.com. The 2nd email does not have a subject. This also means the calendar entry in google calendar does not have a title other than the generic (No Subject). Can this subject be passed to google? I'd like the SERVICE and CLIENT put in the subject.

Thanks!
