How to add generic fallback intent with some message in generic Chat Assistant(Conversation design)

I want to add a generic fallback intent where if bot doesn’t understand user’s intent it goes to the fallback intent and returns the desired text.
I can achieve this by adding “No Match” message in “Prompt” user input, but this has to be done for each block.
I need help in setting a common fallback intent for all cases.

Unfortunately, I don’t think that’s possible, at least not for Alexa. This previous exchange may speak to your issue:


I am building a generic flow, is it possible in that case?

Hmm… can you elaborate on what “generic flow” means? Can you provide an example of what the user says and then what the bot says/does? Otherwise, it’s hard to determine if I know something that can help.
