You can display another GravityCalendar feed on this calendar! To do this, enable the Calendar Subscription Link on the other calendar feed, then paste that URL into this feed’s “Display Events from Another Calendar Feed” setting.

Inside the feed configuration screen, scroll down to the “Display Events from Another Calendar Feed” section, where you will be able to paste the URL of an external iCal feed—or another GravityCalendar feed from your website—and choose a different color for this feed:
