CoursePress: Create "groups/classes," assign a "Teacher" and "Tutor"

I would like to assign multiple teachers to a given course.

I would like to assign a "Course Administrator," "Teacher," and multiple "Tutors" that can answer questions submitted in the course discussion (and Q&A plugin).

I would like Tutors and Teachers to be able to access the "workbook" progress reports for students registered for their course.

Thanks in advance,
