I would know if you can insert a story map within another story map, that is, if I created a story map with the Cascade template can I insert in it a story map which I created with the Shortlist template.
You can embed some story maps inside other story maps. Shortlist could be embedded in a Series, for example, but other story maps can't be embedded inside a Shortlist.
Even though you *can* embed story maps inside other story maps we recommend using this technique sparingly. It's often preferable to simply link out to another story map rather than embed too many things in a single story.
Here's a blog with some more information about how to do this and recommendations: Embedding a Story Map within a Story Map | ArcGIS Blog
