How do I switch to part way through another topic?

I have a need to switch topics half way through a topic but I don't want to go back to the start of the topic I am switching to and have to ask the user the same questions again, is there any way to switch topic and start the topic part way down?

Below is the code I'm currently using to switch topics which takes me back to the start of a topic:

(function execute() {
     vaSystem.switchTopic('/*topic name*/')
})()
