Can I cross-list two separate courses (not sections)?

Community Novice

I teach Clay Sculpture I and II (or sometimes an Advanced Ceramics section) in the same class. I'd like to have 1 Canvas course for them, especially right now during COVID, but the cross-listing instructions imply that they're only referring to sections of the same course. Also, entering the 2nd course as per the instructions isn't bringing up my 14 students from the other course.
