LT Scores and Auto-Green stars

LT Scores and Auto-Green stars

Is there a way to turn off the green stars for any evidence connected to the same learning target that has been given an over all score? For example, science lab reports happen throughout the entire school year and have the same LT attached. After a few labs we know the student has mastered the LT, but lab reports still need to be completed with every experiment. When the student goes to Empower these lab report activities automatically have a green star, students see this to mean they don't have to do the lab reports anymore.
