Not Applicable Button?

Question

Hi there,
I was wondering if there was a way to add a Not Applicable button to one of the interview screens, and if the user selects not applicable, they can continue the interview, and also pass the interview. Or, is this something I need to be writing in my rules. I know there is an uncertain button option in screen building, but that's not really what i am looking for.
Thanks!

Breaking this down into two components.  First, do you want "not applicable" to be an answer that you can/should reason about in your policies and does such a response in fact represent something different than uncertain?  (e.g.  A person is eligible if something is true or if it is not applicable, whereas they MIGHT be eligible when it is uncertain and they are not eligible when the something is false)  If this is the case, then you will need to use a variable attribute (let's assume text) rather than a boolean to represent the four distinct responses (i.e. T, F, NA with uncertain being the lack of a response, empty string / default).  You could then determine a boolean attribute based on "T" or "F" responses (i.e.  "the person's was an active duty veteran") and a separate boolean for not applicable (i.e. "the person's veteran status is not applicable").
The second part is "button" vs. text attribute as assumed above.  If the above 4 possible value response is what is desired I am not sure how you present a button to represent "not applicable" and some other control for "true, false, uncertain" and target the same attribute.  If splitting the controls, I would suggest two different attributes one is the factual "applicable and true, false or uncertain" and the button is used for the "not applicable" attribute (defaulting to applicable unless explicitly set to not applicable by the user and if both questions are on the same screen, use a warning if there are inconsistent answers between the two.
