Facebook's sharer.php - default view

Question

I'm using sharer.php to share an item to the user's wall.

The facebook sharer has 2 views:

Post to profile (default view) :

And when you click on "send as a Message instead you get :

What I'm trying to do is to have the 2nd view (send a message) as the default one. So when the user clicks 'Share this', it would show him directly the "send a message" view.

Is that even possible using facebook? or anything else? maybe executing js code after the popups opens ?

Thanks.
