@RG040N Hey Richard, I think the only way to do that is by passing variables between topic and use that variable to set one in the topic. You can do this with Bot variables easily but there's a drawback - bot variables (currently) only reset if your user starts the conversation over. The drawback with passing Topic variables back and forth is that the topics don't pass certain variable types.
But all that said, I believe that there are some new features that go into public preview in November that will significantly help with this - specifically around the ability to pass and reuse variables.
