This sounds a lot like what we call an "AI check" in a regular Momentic test. These work great on known flows, and are actually one of the main reasons a lot of our customers love Momentic. Mo doesn't replace that; it builds on top of it by adding the ability to discover and test new flows that you didn't previously write scripts for, or don't want persistent scripts for. In the near future, Mo will also be able to propose durable tests that you can rerun later (essentially, exactly what you're describing), which will decrease cost and increase consistency significantly for already known flows.
