Coursepress assign a student to a specific teacher?

Hi Guys,
I would like to assign students to a teacher, I am trying to create user groups but I couldn't find right system or plugin to do it. What I would like to do each teacher are able to see only their assigned students. And I didn't want to create multiple courses for each teacher. I want to use 1 course but in that course there are going to be multiple teachers and they are only going to be responsible with their students. I don't want to let teachers to see all students who is taking that course. Basically I am looking for a plugin that groups the users but only group members can see each other at the dashboard. Do you have any idea?

Thank you.
