Hi Menno!
Guess that's a question that could easily be added in the Teaching with Moodle forum instead, but I'll answer it here.
You could use a Voldaan/Niet voldaan scale instead of a grade, if you wish, just to mark that a specific assignment fulfills requirements.
In the gradebook though, you need to have the grade visible for a student participant to be able to read the feedback.
