Changing ticks in course list to different icons

Hi in the tutor LMS plugin under continue to lesson button, you can add a list of what is included in your course. Can you change the ticks that are in front of the list? For example if you had a video in a lesson could it have a video icon instead of the tick, quizzes, the ? mark quiz icon (that is on the dashboard), the same for assignments and if you were to have certificate on completion on the list the enrolled courses graduation cap (enrolled courses that is in the dashboard). Is this possible please?

Thank you
