Can the R4981-Freight Update ever re-route a shipment


Can the R4981-Freight Update ever re-route a shipment? I know it can re-rate (when the F4941.RATR= 1 but that does not re-route). We are using 3rd party warehouse system (Logpro). We send order information down to Logpro in batch file and we receive a batch interface file back with actual shipment information which we use to batch call E1 ship confirmation(R49500/R47500) then we batch call Freight Update. However, warehouse could pick a different carrier, so we need re-route with new carrier/mode transport to get correct carrier charges. I need a way, in batch, to trigger the R4981 to re-route and honor the new shipper number and mode of transport (that will be on the sales order)
