Clearing quiz marking from already completed quizzes from dashboard

[elphmeister]

A change was made to a published classic quiz which students had already submitted to and been marked. The quizzes that had already been marked are now showing up on the teachers' dashboard to do list to be marked in speedgrader again. Is there any way to have these not show up for regrading, or do I have to manually go in and go through each completed quiz and click Update Score to clear these from the teachers' dashboard to do list?
