Some are, some aren't I noticed. The ones that are (Occupation, Career, Art, etc) will accept anything in a text box. The ones that say "Any Language" or "Any Affiliation" I limited to known ones in the book. Can add more as needed.
Edit: And as I think about it, it's not confirming and just accepting what is in the text box and attaching to the end so it'll crash right now for various dumb reasons due to the complexity and somewhat spaghetti code that is there already. But will be fixed.
