How can I turn off the traditional gradebook and only allow students to view grades by the mastery gradebook?

I am trying to create assignments and use rubrics with outcomes. I want students to get feedback based upon the outcomes and not overall assignment score.  If we are trying to fundmentally shift our grading to standards(outcomes) based grading, then the Canvas gradebook needs to reflect this change. Students and parents will always view the point/average system of a traditional gradebook unless we are able to force them into viewing only the mastery gradebook.
