How do I reset radio buttons without resetting a form in Adobe Acrobat XI?

I am creating a form in Adobe Acrobat XI via Microsoft Windows 7, and on this form I have several "Yes" or "No" questions.  Some questions are not applicable (if you answered this, then skip to question x).  Unfortunately, if someone needs to reset a particular radio button group, then they have to reset the entire form.  The form is five pages long, and I do not have the authority to change the basic content of the form (just make it fillable), so adding a "not applicable" radio button is not an option.  I am a self-taught user, so getting into javascripts may require someone explaining it to me to break things down Barney-style.
