H5P - locking grades and completion status when requirement is achieved

Hi,

Im using various H5P interactions such as Interactive video and course presentations in Moodle. I have them set throughout the course that moodle records when somebody has either completed a H5P activity or received a grade. But the problem I have is, if a person completes an actiivity or receives the required 100%, they can go back to view the activity again and it changes their completion status or changes their grade.

Is there a way that when the required criteria is met, such as activity completion or maximum grade received in the H5P interaction, that it saves that grade no matter how many times the person goes back over the activity?

Many thanks in advance

Brendan.
