How to directly link to a Moodle course when Storyline SCORM ends

Hi there

I am building Articulate Storylines to use as SCORM objects in Moodle.

They work beautifully but for one niggling thing: I cannot seem to work out how to put a link at the end of the Storyline to link directly back to the course in the LMS.  I've tried putting a link in the Storyline itself by linking a button to the URL of the course and it frames Moodle course within the Storyline. I then tried linking from the end message that occurs once you exit a Storyline course in Moodle and it frames the URL in the side window.  

Is there any sort of work around?

Cheers
