The Academic Enrollment data import, Scheme 3 allows you to import using the Host ID, and not by role or name. That said, I inadvertently added Juwan Swan, a user in the Past Student role, at the time of the data import. Given that, is there a request to perhaps require the Role field to add Role to the File Layout Help populated so Past Students are not inadvertently added...or put some other measure in place to help prevent users in non-Student roles from being added via this import.
