How is this still not a thing in Storyline?

Hi MatthewGauthier​.

Good day! 

Published courses can't be edited or reverse-engineered. To open a Storyline 360 project, you'll need to have the original Storyline project file (*.story). 

If you included the source file when publishing your project to Review 360, you can download it by opening the Version drop-down menu and clicking the download link for the desired version. Once the file is downloaded, you can double-click it to open the project in Storyline 360.

Please don't hesitate to reach out if you need anything else.
