[Question] Topic Timeout?

[rmasci]

I have a chatbot running, and I have programming that allows a user to start a troubleshooting session, and each step is a topic. The problem is they may go away, and then come back hours later and try to ask the chatbot another question -- but they're stuck inside the topic they left on which may be a few days ago. Is there a way to time out a topic? So that ten minutes later it goes back to topic=random?
