Canvas Grade Passback for Complete/Incomplete

This is my first school year using Canvas and Formative. I’m using Formatives during Small Groups and have posted them as an assignment in Canvas so that students understand it is not an optional activity.

However, I don’t want to grade the assignments, just check and see if students have completed the work. If I make an assignment in Canvas and set the grading to Complete/Incomplete, when I pass back to Canvas, only students that scored 100% correct receive a Complete. Is there anyway to change the % threshold in Canvas so that students that scored 70% and above get the Complete?
