Use case:  We are using Process Automation to automatically deploy permanent bookings.  When the booking starts I want to run an automation that feeds in the ServiceID of the booking (or the ReservationID which I can use to get the ServiceID).  Tried using the "Created Booking Action" property on one of the nodes in the service definition, but this runs too early, as the booking\service isn't fully formed yet.  Is there another property I can use somewhere that will only run once the booking actually starts?
