Facebook Multiple invites using Requests 2.0

Is it possible to send multiple invites using new Requests 2.0? Documentation as of now saing that 'to' parameter can specify only one user, so it single user or standart request dialog even without possibility to set default filter! It's huge drawback from hidious by nature, but effective in purpose FBML.

Sure.

Look in the docs for Requests 2.0:

Send to Many

From your application front-end, execute:

FB.ui({method: 'apprequests', message: 'You should learn more about this awesome game.', data: 'tracking data: 'tracking information for the user'});

This will open the facebook Dialog:

If you meant in your question whether or not you can filter multiple id's - meaning, you choose the list of uid's to send the request to and not the user - then the answer is no, it's not possible currently.
