View Calendar for a non primary assignment

Summary

Can an Employee with multiple assignments view the work schedule for all their assignment?

Content

In our current configuration an employee with multiple assignments is only able to view their work schedule/Calendar for their primary assignment.  Shifts for their other assignments do not show on the calendar view and it is not possible to 'select' to view their other assignments.  Is this expected functionality or is there a way an Employee can view their non primary assignment work schedules?
