Teacher > Course > Assignments > Assign Content

As a teacher I would like to have a user interface that more clearly shows what LESSONS have been assigned and to filter out already assigned lessons.

Currently, the Assigned/Scheduled label appears next to individual assignments. 

It would be helpful if, when all assignments in a lesson have been assigned/scheduled, that label appeared next to the lesson as well, so teachers don't have to open each lesson to see what's been assigned.

It would also help if we could click a box that would filter out assigned content and only display unassigned content.
