I understand that, Saguaros.
But what I'm trying to do is make the process much quicker by duplicating a course, and then selecting a SCORM that has already been uploaded but not used by another course (as mentioned above, unused SCORMs appear on the SCORM Manager screen, but not on the Edit Course screen).
If that is not possible, it's ok - I'll just use the longer approach, but then that option of "Replace SCORM" on the course manager screen shouldn't be offered, because it doesn't do anything.
Tks,
Serge
