Let's say I have a lead that downloaded some information, and I drop them into a stream for some follow up information. Subsequently, they download a trial of our product, which is of higher priority to me. I have a trigger that moves them into the higher priority stream, which they exhaust. Is there a simple way for them to move back and resume? Is that standard behavior? I'm thinking I might be able to create a smart campaign that looks for any exhausted leads, and if it finds them, check if there are any paused streams, then resume. Am I thinking about this the right way?
