is it posible to preselect multiple users (where is Naitik Shah) in this dialog? Thanks!

When preselecting, you can only specify 1 user ID. If you don't specify any user IDs, then Facebook pops up a friend select dialog and the user can select up to 50 friends. If you want to send to multiple users, the user has to do the selecting.
