Add and Analysis the status in EDI 214 from The Home Depot to Bowden Transport to up new Appointment notification

There are 2 questions I want to clarify on this issue:
1st question: May you help me analysis the "status": "delivered" and "status": "in-transit"?

2nd question: Do we have any way to create a new status for Delivery Appointment notification and Pickup Appointment notification with the line data for EDI 214 from Bowden to The Home Depot Logistics?
