Adding multiple events to a single ics Calendar file

Question

I'm facing a weird problem here. Whenever I generate an ics file with a single event and open it, the event automatically integrates nto my outlook calendar. That's very fine. However, when i add more than 1 event to a single ics file, and when i open it,
it creates a new calendar in Outlook, doesn't integrate into my default outlook calendar. Please help me with this issue.....
