Know what Id really love? Some way to, on returning from a flow, say "subflow_a" take the returned variable say workflow.subflow_a.somevar and directly copy it into the parent's workflow variable. I run the javascript to do it (workflow.somevar = workflow.subflow_a.somevar) after every flow but its easy to forget and annoying. Even a set variable card, which the botpress ai seems to think is a thing would be nice to have.
