Calendar on Mac - how to combine same event listed on multiple calendars?

I have several calendar accounts - my work email account (exchange), my work group account (google) and (home (google). Many events that take place during work day need to be on all 3 calendars. In Fantastical, the event would be listed once, with the color code showing it is on more than one calendar. In Apple Cal it shows up 3 times which is really annoying. Is there any way to combine events? Or is that in the works perhaps?
