How to Tag someone in Facebook post

Hi,
using the pro addition and mostly posting photos.

Is there an option that I can add a Facebook-Tag to the text?

e.g. currently it is:
%TITLE% – details here- %URL%

but could it be:
%TITLE% – details here- %URL% – great post by @name-of-facebook-user-or-page .

In other words, is there a way to tag a facebook-user-or-page in the Message-Format field ?
