Display total qty sold of each item of each store

Would something like this work?

SELECT
        a.[Item#],
        SUM(QtySold) AS [Sale Total],
        SUM( CASE WHEN b.[Store#] = 'Store A' THEN b.QtySold ELSE 0 END) AS [Store A],
        SUM( CASE WHEN b.[Store#] = 'Store B' THEN b.QtySold ELSE 0 END) AS [Store B]
        --- etc
FROM
        ItemMaster a
        LEFT JOIN ItemMovement b ON
                a.[Item#] = b.[Item#]
GROUP BY GROUPING SETS
   ( (a.[Item#]),());
