[CoursePress Pro] Track student progress without assignments

Our courses are used by businesses for employee development. They are not graded and students do not turn in homework. There are no assignments that I can track (all is self-managed, self-reported). However, HR departments and Team leaders/managers often want a report of student progress. How many people have accessed a particular unit, etc. This is a critical feature yet I do not see how to track as the workbook is not something they turn in. Rather they download and fill out on their own.
