These escalations are activated when a user does an "In PROGRESS SAVE" when FIRST starting a workflow project or when a user transitions back to the (start) state. Other than that, this escalation feature functions the same as those configured for other states.
Configuring the escalation in the start (Start) state is as follows (similar to how other escalations are configured):
