How do you handle screen numbering in branching scenes?

I know I'm a bit late to the table for this discussion; however, I have had similar issues in the past, so I thought I would share my suggestion. I had a module with a set of 10 scenarios - there was a main menu, then ten sets of 3 slides for each scenario - a video slide, a summary slide and an assessment question. The menu was Page 14, then Scenario 1 consisted of pages 15,16 & 17, but then it was back to Page 14 every time the learner returned to the menu, then Scenario 2 consisted of pages 18, 19 & 20, then back to page 14 for the menu, and so on.

To solve the issue, we removed all the scenario slides from the menu and manually numbered all 30 scenario slides as Page 14, as we didn't need the learner to jump to these directly. Effectively making the 30 slides act like layers from the Page 14 menu slide.

Hopefully, the attached screenshot of the relevant part of the story view makes sense - I've added red text to show which slide is Page 14 and which is Page 15 - all the rest are manually numbered as described above.
