Grade Calculator Adjustment Option

I’m loving the new BetterCampus update, but would really love if I could have a place other than the “what if” section (which hasn’t been working for me) to input the grades I know I have in each class like in the old grade calculator. I have multiple classes for which my grades aren’t in the canvas grade book because of how my school sends out grades, and it’s impacting my GPA so that it’s not accurate. I’ve also tried multiple times in the “what if” section of the grades tab to input the grades in classes whose grade sections show as a - - because my teachers haven’t put them in, and am unable to edit that section either.
