Restricting navigation on specific slides only when they are not embedded in a quiz

Storyline 360: How to Restrict or Lock Navigation - Articulate Support

The above article helps answer how to "unrestrict" a specific slide, but is there a way to create a locked slide as a trigger where they must get a correct outcome to progress for those slides only.  I am re-programming an existing module and there are far too many slides to do the opposite approach easily (for now).  

Thanks!
