Customize report analytics

Hi.

I have scenario-based course with a pool of 45 questions. Not all questions will be served. If the learner picks the right path, they will only be served 15 questions. I'm wondering if there's a way to filter the report sent to the LMS (when Process Test/Survey action is involked) so that only the questions served will be reported to the LMS. Right now, it is sending everything including the questions not served (and they show "blank" as response).

Thank you.
