Subtract Values From Different Rows Within Query

I have a query that uses rollup to get totals and top 101 to restrict the rows to top 100 rows plus the total column. The total column shows total for all rows not just the top 100 which is exactly what i need. The only thing I need now is a row that shows total for all rows that have been excluded, or the total row - total of the top 100.

Here's the query: (Biggest factor i have to keep in mind is query speed.)






Code Block

WITH CTE_name AS (
SELECT TOP 101 b.name,
SUM(ISNULL(CAST(b.launched AS BIGINT),0)) AS quantityPrepared,
SUM(ISNULL(CAST(b.bounced AS BIGINT),0)) AS bounced,
SUM(ISNULL(CAST(b.delivered AS BIGINT),0)) AS delivered
FROM dimension tt
INNER HASH JOIN batch b ON (b.batch_id = tt.batch_id)
WHERE tt.datelaunched >= '11/19/2007'
AND tt.datelaunched < '11/20/2007'
AND tt.id = 1
GROUP BY b.name WITH ROLLUP
ORDER BY SUM(ISNULL(CAST(b.launched AS BIGINT),0)) DESC
)

SELECT
name,
quantityPrepared
bounced,
delivered
FROM CTE_name
ORDER BY 2
