They need to send the user to shipstation in one of the custom fields. As an example currently It sends sales rep into custom field 2, can we send the “User” instead of the “Sales Rep”. Please refer to the screenshot below for guidance. User means the user appears under the activity log in the sale orders in Cin7 Core.
