Want to add to the sorting options in the "message students who..." feature in the gradebook.  Currently, you can message students that score less than or more than or haven't been graded when doing a complete or incomplete assignment.  I use the complete or incomplete assignment as evidence towards their grade but don't add points to the assignment, so score less than or more than doesn't help me.  I would like to be able to message students who scored incomplete to remind them to complete.
