Hi Pierre,
I dont know of a way to do this automatically, however there are two ways you can achieve this:
1. create your own layers, call them "Success" and "Failure" and then just ensure the triggers are pointing to them correctly; and everything will work fine - or...
2. create a new RESULTS slide anywhere in your course, and copy/paste the Success and Failure layers across to your actual Results slide.
I would go with #1 above, and use the INSERT ribbon bar to add all the bits you want - like user score, passing score, buttons, etc.
If you go with #2, its easier for layout and design, but just remember you will need to swap over all the text output and triggers on the copied layers, so that they show the actual Results data that you want.
