Prefixing Event Title

Feb 15 at 12:03 PM
Is it possible to add a custom prefix to each event?

Background: I want to push each entry from my work calendar (outlook) to my private calendar (google). I still have many calendars at google (round about 15) and many different colors are used. So, it would be very nice to add e.g. "WORK: " as a prefix to the event title, so I can see what's a work entry
