Write to "Customer" notes field via automation rules
Seems like a basic oversight that you can write to pretty much any notes field via automation rules, but not "Customer" field.
Hi, thank you for sharing this! That field is primarily for notes from a customer to you, the merchant. What kind of information are you looking to add to your orders automatically?
Custom fields 1, 2, and 3 might be a viable option as they can be used in many other places throughout ShipStation.
