Tracking completion of rated quiz slides in LRS in addition to the completion of the whole quiz

Hi,

I am currently using storyline quizes together with learning locker lrs and a custom plattform to generate reports out of it. I want to know not only the completion of the whole quiz (which works perfectly) but also the result of each slide. The quiz is currently configured to measure process not based on slide views but on the result slide. Now to be able to improve the training, I want to know which slides (topics) had been the ones with the most problems / incorrect answers. So here is what I am currently wondering:

• Is there a way to report the result of each slide? Currently, storyline generates statements for each processed slide with verb "experienced" but without a score or completion details.
• Is there a way to define the ID of each slide? I can do so for the main course, but the slides have a very technical ID like http://#8653/6GV0MNQB0fi for a course that has ID http://#8653 
• Maybe I can add details about the slide (object) like a human readable name, too?!

Thanks,

Mirko
