We have the same request. We would like the answer options to be Yes, No or NA. Setting a Confirmation Rule for each workflow would be helpful. Is that possible? Or can you explain in further detail what you mean by setting the questionnaire to "limited"?
Being able to edit the choices would be the best solution. I will go to the IdeaStream thread and comment.
Thanks.
The approach is basically: have the questionnaire in a lower profile, then at parent level run Confirmation Rules that will decide which answers are actually acceptable and react accordingly. It's definitely doable, although the rules might be tricky to write for non-coders.
