Simulation navigation ideas

Hi – looking for any feedback or tips on how to create more intuitive navigation for simulations. It would be great to have hot-spot elements on the screen indicator progress, so that users could click back to a previous screen, but there’s no way to position those from the editor. I’d like to allow the learner to repeat a step but I’d like to avoid separate back buttons on every screen. Maybe a ‘previous screen’ variable then updates? Any suggestions would be appreciated.
