Of course it could! That's just a matter of combining the code from posts #4 & #14. It's up to you to decide which you want to extract first - the Content Controls or the Formfields - you can't easily extract them in order if they're interspersed.

However, you should not be using Content Controls and Formfields in the same document anyway - they're not designed to work together and doing so can cause problems in the document.
