Hi @ChelseaRozek -- Yes, you can link to any heading or subheading in your story using the process outlined in How to create a link to somewhere else in your story
Map actions are also available if you want to toggle layer visibility. You can learn more about them here: Supercharge your stories with map actions
Can you share more about how you are using 50 map actions in the same story or share a link to your story so far or the classic story you are trying to replicate? 50 map actions seems like a lot for a single story, so maybe if we know a little more we can recommend another way to think about organizing things?
