Option flag for adding the .ics (ical) file to an event alarm

[arescope]

Dear Indico Support Team,
I would like to know if it is possible to attach the .ics file in an alarm email corresponding to an event (?).
For the moment, one can include a text version but not the .ics file (via Tools -> Alarms -> Create a new alarm email).
Potentially, two files could be chosen (same as the ones available on the event page):

• the "Event calendar file";
• the "Detailed timetable calendar file".

Thanks for letting me know.
Best regards,
