I'm trying to build a bot that answers questions (about restaurants, etc.) by region. Therefore the user chooses whether he wants to ask about the north of the city, the south of the city, the center of the city or does not matter. If he chooses North, Central or South, he arrives at a work flow in a folder where there is an knowledge base found only for that part of the city. But if the user says that it doesn't matter to him, I want him to be able to ask questions about all the knowledge bases that are in the different folders (so as not to produce just a duplication of the knowledge bases).
