I'm not sure if this is an NMAS question, an eDir question or UserApp,
or all three.

Okay, so a lot of websites (ironically, Novell included) have
challenge/response questions similar to this:

You must choose 1 item from the following three "sets"

So choice 1 will have a pulldown of like 4 questions and you can pick
one. And Choice 2 will have like 5 questions and you pick one of those,

Where is this done?

In NMAS UP in iManagler, I do not see the ability to do this.

So is this feature/function purely a UserApp or some other custom code
