Single Event on Multiple Calendars - Mountain Lion

Does anyone know of a way to have a single event show on more than one calendar without having to manually recreate the event. For example say I have a few icloud calendar set up. One called home stuff, another called major eventsm and another called training. Then I have an event that I want to put on both calendars such as Championship Tournament. Is there a way to have this event associated with both the Training and Major Events calendars so that if I edit the event on either on it will show up on the other?

I realize this may not be possible because of how Calendar indexs events and calendars but who knows maybe someone out there has figured out a way to do it.
