Can I use with “User submitted post”?

I am using Guest Author on a blog, and I also use “User Submitted Post”, a plugin that create a form so the editors can submit posts directly from the site without having to use wp back office.

That plugin let me to add custom entries to the form, so I was wondering what code should I put to create entries for guest author name, pic, url and bio in order to submit them from that form? Is that possible?
