Make more performing the query.

Hello expert.
There is a way to speed up the following stored procedure:

ALTER PROCEDURE [dbo].[UpdateSalesOrderDetailFields]

AS
BEGIN
UPDATE    CurrentSalesOrderTemp
SET           AD_Mode = vBM_BillOptionHeader.OptionDesc1
FROM        CurrentSalesOrderTemp INNER JOIN
                  vSO_SalesOrderHistoryDetail ON CurrentSalesOrderTemp.SONo = vSO_SalesOrderHistoryDetail.SalesOrderNo INNER JOIN
                  vBM_BillOptionHeader ON vSO_SalesOrderHistoryDetail.BillOption2 = vBM_BillOptionHeader.BillOption
WHERE     (vBM_BillOptionHeader.BillOptionCategory = '2')

UPDATE    CurrentSalesOrderTemp
SET           TempUnits = vBM_BillOptionHeader.OptionDesc1
FROM        CurrentSalesOrderTemp INNER JOIN
                  vSO_SalesOrderHistoryDetail ON CurrentSalesOrderTemp.SONo = vSO_SalesOrderHistoryDetail.SalesOrderNo INNER JOIN
                  vBM_BillOptionHeader ON vSO_SalesOrderHistoryDetail.BillOption2 = vBM_BillOptionHeader.BillOption
WHERE     (vBM_BillOptionHeader.BillOptionCategory = '1')

UPDATE    CurrentSalesOrderTemp
SET           FiberCableCode = vBM_BillOptionHeader.UDF_CODE
FROM        CurrentSalesOrderTemp INNER JOIN
                  vSO_SalesOrderHistoryDetail ON CurrentSalesOrderTemp.SONo = vSO_SalesOrderHistoryDetail.SalesOrderNo INNER JOIN
                  vBM_BillOptionHeader ON vSO_SalesOrderHistoryDetail.BillOption2 = vBM_BillOptionHeader.BillOption
WHERE     (vBM_BillOptionHeader.BillOptionCategory = '3')

UPDATE    CurrentSalesOrderTemp
SET           FiberCableDesc = vBM_BillOptionHeader.OptionDesc1
FROM        CurrentSalesOrderTemp INNER JOIN
                  vSO_SalesOrderHistoryDetail ON CurrentSalesOrderTemp.SONo = vSO_SalesOrderHistoryDetail.SalesOrderNo INNER JOIN
                  vBM_BillOptionHeader ON vSO_SalesOrderHistoryDetail.BillOption3 = vBM_BillOptionHeader.BillOption
WHERE     (vBM_BillOptionHeader.BillOptionCategory = '3')

UPDATE    CurrentSalesOrderTemp
SET           ESPGroup = vBM_BillOptionHeader.UDF_CODE
FROM        CurrentSalesOrderTemp INNER JOIN
                  vSO_SalesOrderHistoryDetail ON CurrentSalesOrderTemp.SONo = vSO_SalesOrderHistoryDetail.SalesOrderNo INNER JOIN
                  vBM_BillOptionHeader ON vSO_SalesOrderHistoryDetail.BillOption8 = vBM_BillOptionHeader.BillOption
WHERE     (vBM_BillOptionHeader.BillOptionCategory = '8')
END

Any help will be appreciated.
Thanks in advance
