As a moderator, I might need to override a grade that has been allocated/calculated for a student. At present there is no ability to 'override' an existing grade in GoReact - any grade inputted by a reviewer role is combined with other reviewers' marks and an average is calculated. Without the override capability to support the concept of moderation, the GoReact grading can't be used in larger classes with multiple assessors, and the activity has to be marked in the LMS.
