Adjusting how to Score a Quiz and passing this to LMS

I have a quiz marked out of 54 points.

To 'Pass' learners must score between the range of 15-19 points.

Anything above 20 and under 14 is considered a 'Fail'.

I am fairly new to Storyline and can see that when scoring the quiz questions, I can only set a passing % rate but this wouldn't work for my example above because it is a points range.

Is there a way to customise the scoring and report this back to the LMS?

Thanks,
