I want to remove/hide certain assignments from students to do lists.  I understand that, since I will be manually entering the grade, that the assignment will appear in the gradebook.  That's okay. However, most of my students live and die by the to do list and this assignment is strictly used by me to send grades to our SIS which does not support mastery paths.  I absolutely do not want students to see this assignment EXCEPT in the gradebook.  By completing their mastery path, they have done what they need to do.
