Reprocess specific masstransit message in a new saga and finalize current

I'm using Masstransit 5.1.4 with sagas. I have a saga where I want to implement the following behaviour:

• When a StartMsg is received -> transition to Active state
• While in Active state, several events are processed
• If a StartMsg is received in this state, the current saga is finalized and reprocess the StartMsg within a new saga instance

How can I achieve this?

Here is a small pseudocode

Initially(
    When(StartEvt)
        .Then(...)
        .TransitionTo(Active)
    );
During(Active,
    When(OneEvt)
        .Then(...),
    When(AnotherEvt
        .Then(...),
    When(EndEvt)
        .Finalize(),
    When(StartEvt)
        // Finalize current saga
        // Transition to initial state reprocessing StartMessage bound to StartEvt

You would need to finalize the current saga, and publish an event (or send it, to the same queue, using Send) which would create a new saga instance. In this case, you'd also need to use a saga repository which would properly lock around the correlationId, so that you aren't processing two messages at the same time for the same correlation, which would likely find the existing instance before it was deleted.

You could NOT do it in a single message handler, although, thinking about it, why would you need to finalize, versus resetting the current saga instance back to an initial state?

Also, you might consider using a separate correlationId for the subsequent startMsg, so that you can keep track of each "attempt" at finishing. Otherwise, you won't know if late messages from a previous attempt would confuse the actual state of the current attempt - since you'd have no way to distinguish them.
