I'd like to create a chart telling me the top sources for an event, e.g. "SMS Signup." I've created a chart for this event with a breakdown by referrer. The problem is -- this is only half the information. Many times the referrer field is left blank but there's information about the source in the url (i.e. if it's a UTM). Does anyone know of a way I can create a custom breakdown that merges these two properties?
