Faceboook SDK - FB.Feed without user's customization

Hello forum !!!

This should be an easy one: is it possible to post a FB.Feed without giving the possibility to the user to add a comment?
Basically when you call FB.Feed a window created by the Facebook SDK will appear with the preconfigured feed graphics, a textfield in which the user can add a message and all the buttons to post and set the privacy of the post.
Is it possible to not show the textfield or to nullify the inserted string before to post?

Thank you !!!

 

Just in case you are thinking about that, the answer is no.
And also if it could be possible it is forbidden:

Here is the complete policy.
Didn't know that. So, also picture captions are not allowed if you don't give the possibility to the user to write/revise it before to post.

Hope this will be helpfull ;-)
