I need one extra function in Facebook fan page

I need one extra function in Facebook fan page. A need my fan page to invite attendees and maybe attendees of an old event in the fanpage to a new started event. It’s have to be very easy so I only push a button. Just Pick the old event and pick the new one and as I push the button all the attendees and the maybe attendees from the old event get invited to the new one. It’s have to be very easy so nothing can’t go wrong…. Its have to work with 2-3 years old events and event from other fan pages. Attendees from 1-10 000 people i is not importent is a button it could be a script or something on my computer. i want to choose a fanpage and a event on this [login to view URL] a wont to invite all the attendees and maybe attendees to one new started event ex... if i had a studentparty in mars.

Do you understand what i mean? i need to invite attendees of an old evfent to the new one.
