From Address field needs to be Customizable

There needs to be a modification on the data, the from company field needs to be customizable to each client. instead of blue express which is the WMS name it should be the OMS client name and that change should not affect to other client from company address field. In this case it should be crossDocking Fulfillment. Currently this can be done only on the return labels. Please see images attached Thank you in advance.
