Linking multiple Presenter files

Is there a way to link multiple Presenter files?  Example: The course consists of five modules.  Each module is a separate Presenter file.  At the end of Module 1, can a "finish action" or link, etc., launch Module 2?

I am working with Presenter files that were created by someone else.  The last screen of the PPT/Presenter file contains a Flash file that has the finish action set within the Flash file.  I cannot edit the Flash file, so is there a workaround to delete the last screen (with Flash file) and replace with a finish action within Presenter or anything that would launch Module 2. Or is it better to rebuild the course and create one course containing all five modules?

Many thanks!
