we had the same issue and what we did was create a report from the site logs source and set the search to have the event class name contain "Submitted SCORM status"
The columns we included on the report were:
- user name
- course name
- course time
- context
- time
- description
It, as any workaround does, comes with some caveats
- the SCORM has to have it's activity completion set
- site logs only go back four years
