Handle "else" intents in stories

Say I have a story which branches into several different paths based upon user input. I may write the stories based on the input I expect, but what if I want a “catch all” branch to ensure a fallback action?

I do not think this is currently implemented but I am comfortable experimenting with the source code. What files should I start looking at? Probably memonization policy? The featurizer?

Has anyone else had experience with anything like this request?

@DylanRedfield you can implement a fallback action based as an action which will check how confident NLU and Core predictions were. Have you looked into that already? You can find some documentation on that here.
