Protecting individual course Units from CoursePress

I want to use Protected Content to protect individual courses and course Units.

Protected Content allows you to protect actual Pages and Categories. CoursePress courses and Units do not show as "Pages" in wordpress "All Pages."

I believe the display of courses and course units are dynamically generated using the database and template files.

How do you use Protected Content to protect 1) individual courses and 2) individual course units?

Thanks
