Here’s the scenario:

We have two courses: One for All Staff and one for a Select Staff. We have an enrollment rule that enrolls someone into the All Staff course when they join an automated group (usually as a new hire).

We had a person, who was a rehire (and added to the group) that was assigned the All Staff version even though they had been enrolled in the Select Staff version. 

Is there a way to say, “If enrolled in Course X, do not enroll in Course Y”?
