We have a situation where a large company wants to partner with us on our courses (for a lot of money), but they also want the ability to monitor "their students' progress" within our membership area. It's kinda like how a teacher would monitor their own students' progress, but not every student in the whole school. In my mind, these "teacher" positions could route through the Collaborators or the Team Members functionality, but I don't see a way to limit their access to just a specific set of courses or students.
