A Button to Toggle Between View All Comps vs. Graded Comps Only

Please add a checkbox or button that toggles on both the teacher and student view of an individual student's grades.
One view will say "view all graded competencies" (and it will show the current long-list view of all comps in the section).
The other view will say "view graded comps only" (and all comps with a "-" will not be shown).
