We need the ability for teachers and admin users to be able to recalculate quarter or semester GRD grades after the grades have been initially posted by the teacher. For example, if a student turns in missing work and the teacher needs to adjust the grade, we'd like them to be able to make the changes to the assignment grades as usual but then just hit a button to recalculate and update the GRD grades instead of going through a multi-step/multi-screen process.
