Is it possible to aggregate multiple calendars into a single one? For instance say I have one calendar for conferences and another for release schedule. I would like to keep them separate but also have another calendar which combines the two. So that people who are interested in just conferences can conveniently subscribe to the calendar that does not include the release schedule. And so that people who are interested in both the conferences and the release schedule can subscribe to a single calendar instead of two.
Thanks for the help!
