Ok....I think I figured out a method. I have 2 or more identical courses with unique course ID numbers.
Example: Hard copy 45 hour Agency Course 1 Parent Metacourse Online 45 hours Agency Course 2 Child Metacourse
I didn't need 3 courses, only 2....Course 1 has the content, Course 2 is 'not visible'. Students who purchase Course 1, enter Course 1. Students who purchase Course 2, are enrolled by metacourse in Course 1.
I think it works.
