Sliders as Progress Meter - Change state of radio button to visited only once no matter how many times visited
I'm using a slider as my progress meter with triggers and variables based on this fantastic share by Carey Glenn in this thread. I love how it works and looks so seemless to the learner. However, it requires that the slides be set to "resume to saved state" because it uses a Visited Flag/radio button to track slides visited and adjust the variables.
That's causing issues because I have slides that advance automatically. If a learner gets out of a scene and goes back in to review, they can't go back to any of the slides that have already advanced. But if I set it to "reset to initial state" the slides can be counted more than once.
Is there any way to make the state of a radio button count only once without setting slides to "resume to saved state" or is there another way to accomplish the progress meter with progress bar?
I've attached one section of my course that hopefully makes what I've explained clear.
