Rise and Storyline blocks completion

Hi

I hope someone can help with this. We have a course with multiple pages and a SL block on each page - pointing to the same SL file hosted on the web. Its the same file each time because we track progress, states, variables and display info like current score, name etc. on various slides.

We also need each slide to be completed to unlock the completion button below the block. 

Does anyone know if the trigger in SL to complete course is detected by rise when its fired, or is it retrieved from the browser cache. So if I put a trigger on each slide to complete when that slide is done, will rise unlock at that moment, or will it ALWAYS be unlocked as an earlier slide was completed and it gets that info from the cache?

If the latter, can you UNFINISH a course with a trigger?
