I have a few entities that are design to get user preferences. However, I would like a user to respond with "either" or "any" or "no preference" to indicate that they have no strong preference either way.
How do I accomplish this? If I train one of the entities to do this, the system will always register those responses to that one entity.
The use case will be based on a question and answer situation. I.e. the bot will ask, "do you have a color preference" and the user should be able to respond with "No"
