Assign Roles Using Rules (similar to Auto-Enrollment)

We would like to assign a Role based on certain criteria. For example, our API brings all Supervisors in as an Admin; if they are an Admin they need permissions to enroll users in a course.

So if they are a Supervisor/Admin then we would like them to automatically be added to the Role we've created for adding enrollments.

This seems like it would be useful for many organizations, being able to automatically set Roles based on a Users profile, especially if they are bringing users in through an API or User Import.
