[ARCHIVED] Gradebook Setup

[jacnol]

So I'm new to Canvas (our school just got it recently). And I had a question about setting up my gradebook. So in years past I've used a system where I assign a student a letter grade for an assignment. In my system an A = 95%, B = 85%, C = 75%, D = 65%, F = 55%, and M (Missing) = 50%. When I tried to set this up I can't seem to get it so that an A is a 95% rather than a range of possible percentages. Is there a way to make it so I can assign a letter and it is that specific percentage? 

I've included the grading system I'm currently using and when I used my test student where I graded an assignment as a B it made it an 89% in the gradebook, but I want a B to equal 85% exactly. Any help on this would be great.
