We currently have about 10 active engagement programs and are developing a survey page that we will include in our emails that will basically ask prospects what content they would like to see. If they select a different topic(s) than the stream they're currently in, we would like to pause them in the current campaign and add them to a new campaign(s). What is the best way to do this? I'm struggling to find the right mix of flow steps. These are set up as individual programs and not separate streams in one program.
