[Plugin: Events Manager] Insert a step before the booking

So here is how we have the current setup. Member logs into our wp site and then clicks on “Book Now” button to attend an event.

What I would like to do is that a member logs in to wp site and click on a button “Tweet this event to get free admission” when they click on a button, they login to their twitter account, tweet a message, which will then allow them to book the event.

Is this possible?
