Editing output element of quiz app

Hi, I am looking to edit the output of the table .opigno-group-progress-course-quiz that tracks the users progress through the course. I need to change the title of the lesson for an icon, (I have added a new image field to the lesson content type). I can see that the table is produced from the opigno_quiz_app_module - but what is the best way to override this output? Thanks, Dave
