Including 2 events in a .ics file

Hello, 

Question on .ics files: 

I can edit my .ics file to add a second event, however when I double click on the .ics, only the first event shows up. 

If I drag and drop the .ics into my outlook calendar, I see that all the events are updated. But this is not ideal as users may find it difficult to save the file, then drag and drop etc.

Double clicking on the file would be ideal, let me know if users can double click and save multiple events.

Thanks,

Raji
