Behavior Tree - how to link a node back to a previous node


I have a dialogue system set up with behavior trees. I would like to link some of my nodes back to previous nodes so my character can ask several questions.
For Example, my character is able to chose one reply amongst several, they pick the first one, the NPC replies, then it would link back to where they were able to ask all the questions. I could not find anything like it and I really need this otherwise I would have to copy paste my conversation over and over again so the character can ask all the questions.

Did you find an answer to this?
