I think that You're using the wrong interface for the job you want to do here!! I would personally not have used a GPWiz. I think you really need to be using a Keywiz in this instance, as far as I know, that would solve your problem.
That said, you might want to mail Randy and ask his advice on this, or hope that he catches this thread and helps out here.
