Is there some way I can trick Canvas into a very simple lateness penalty of 50% if the item is late at all?  None of this incrementally increasing penalty by hour or day?  I thought I was doing this by setting "lowest possible grade" to 50%.  But, I see that when a student earned 2 points on a 3-point assignment that was submitted late, they ended up with 1.5 points posted to the gradebook instead of the 1 point they should have gotten (50% of 2).  

Is there a way to make Canvas do this very simple algorithm of, "Late = 50% of earned grade" ???  This is how my policies on my syllabus are and I thought I had set up Canvas correctly (see above), but now I see it's treating everything that's late as if it were a perfect score whose only crime was being late.  Thanks!
