Well for me at least it seems tricky.
I have a slide with three options. When the user clicks an option, he is redirected to a new slide as I can't use layers as I would like an individual voice-over per option. The slide itself looks nearly the same though.
After looking at the slide I am redirecting him to the "source slide", so that I can have a trigger to ensure that the learner looks at all options before moving on.
But it isn't really perfect as clicking the "next" button is a little cumbersome. It would be nicer if the learner didn't realise he's being led to different slides.
