I run a event management company and the way i work is i have my main website (the website of my company) and i have one website per event to give them a very distinct and unique feel. 

I run all of the websites and events through odoo and i use the events module to organize them. 

Now, Obviously the event has to be displayed on its corresponding page, but i also want it to show up on my main company page. How can i make an event appear on multiple websites?
