Custom URL Redirect after quiz completion

Hi, for SEM purposes, I am needing to have the quiz redirect to one of two different pages upon completion based on pass/fail. At the moment, I am utilizing the ability to deliver two different messages, but it delivers within the same url. Does anyone know if this is possible to force a redirect to a different thank you page?

Thanks!
