Is there some sort of "passepartout" intent?

Hi! I need some help… How can I create an intent that takes whatever string the user passes, so that in the next action I can save it?

The reason is that, in the previous step, after a selection from a database, I give the user the possibility to choose between very different words or values, which change according to the user’s previous choice. I would need something that takes whatever input it gets, doesn’t confuse it with a different intent, and moves on in the conversation so that in the next action I can save his choice.

For example the problem is that this string could also be a yes or no which would be confused with my intent affirm / deny making me jump into the conversation, or some other intent so I need to take any string and move on.
