When a course is part of a curriculum, I can't seem to get it to list as an independent course as well for the same audience. It should be available as part of a curriculum, but ALSO as an individual course in the catalog. (Technically, these could be in different categories!)
This feature is available when editing a template. It took me quite a while to find it.
Open the Setup menu and select Templates.
Select the template and click the Edit button.
Select the Courses tab.
Expand the My Course and Catalog section.
Uncheck the Hide Courses outside Curricula option.
Please excuse the typo - I meant CATALOG
