Welcome to our community, Eric
Likely that is something only the Captivate development team
would be able to assist with. I'm doubtful you will be very
successful in implementing this. For one thing, I would think that
the development team would be somewhat reluctant to assist with a
solution that would seemingly make it appear that you or your
company had created Captivate as your own application.
Out of curiosity, why do you wish to avoid using the
Captivate user interface?
Cheers... Rick
