Looked around and couldn't find an answer for this.

I realize I can allow Anon posts of News items as well as Anon posts of comments.

What I would like is instead of just saying "Anonymous" just requiring that they type a name or something before they post a comment. Still anonymous, but at least have to type Tom or Joe so as to tell the different Anon users apart in the comments of a News item. Is this possible already or something that would have to be customized?
