I can answer having helped implement waybill systems on the Mopac in 1974.  The special instructions such as ‘do not hump’, ‘unload on right side’, etc were added to the computerized waybill and these notations were automatically added to switch lists and work orders.  Other Class 1’s were doing the same but I’m not sure of their timeframes but the mid to late 70’s would be a good guess.
