Customize Bot Answer for "I didn't get that. Try rephrasing your question or start over."

It would be great to have more opportunities to customize the chat bot.

We are using the bot for the instagram connection. Here the users answer on stories and just write "wow" or "nice". Or they mark us in storys. Now the Bot always writes "I didn't get that. Try rephrasing your question or start over." - The customers do not understand this and are going crazy/angry. 

We would prefer, that the Bot asks "Hi, I am a chat bot. Do you have an issue? Please press "Yes" or whatever. It should be a part in the flowbuilder. Or the bot creats a ticket.
