I'm trying to set the shippingmethod in customer -> preferences -> shippingmethod, but running into trouble. I want the field to default to "more" for all customers, so that everytime the user enters a sales order for that customer, the value in shipping->shippingcarrier is "more". When trying to do a csv import update, the field does not appear in the list of fields i can update in the customer record. Any tips on how I can get this done? thanks.
