custom field fed by ical feed

Is it possible to add a field to the default Time.ly calendar plugin that is fed by an iCal feed variable?

For example, I want to add a field for event’s called Description, and that is also the name of the feed variable. Currently when you subscribe to a Timely calendar feed, it picks up the page text from the WordPress page that it is embedded in as the description. I want to replace that both in the feed and on the calendar view.
