How to import a SCORM file into Articulate Storyline?

Hey there. I have a similar challenge. There is a huge amount of courses, designed in a different authoring tool. Now I would like to rework them. However, I only have access to the SCORM files. I`m wondering if there might be a workaround to at least get a quick start. For example: Is there a way to export a SCORM course into a PPT-file, I could then import into Storyline or continue to work on it using the Presenter? While I assume a lot of the interactions probably will break, it would already help a lot to have text and pictures (kind of) in place. Any ideas?
