[EventCalendar] Creating events outside of posts

[Mommy Poppins]

Hi, I've installed EventCalendar3 and am looking forward to using  
it.  i would like to be able to both have events from posts and  
additional events that I don't post about included. Can I create  
events in iCal and have them appear in the event calendar or is there  
any way to create events without creating specific posts for them? THX
