For teachers of K-12 students it would be very, very helpful for teachers to be able to message students a list of every missing assignment in the course, from which they could click directly to each missing assignment. Ideally, this would be as simple as the great messaging that currently exists for missing individual assignments.

 I realize that students can find this information themselves, but they cannot always be trusted to do so.  This addition would make my life as a teacher of middle school students much simpler; when students have many missing assignments, 15 individual messages are far more overwhelming/less helpful than one single one with all the information they need.
