Is it possible to delete the check for positive integer in the rubric's criterion?
I want to be able to have a criterion "late assignment" -x. The late assignment is per day (max 3 days) so I also wanted to have 4 rating "-x*3. 3 days late" etc...
The problem is that there is a check that the integer value is not negative and if it is the value is changed to 0.
This should be a straightforward change.
