qoq summary rows

Hi All,

I have a complex query putting multiple tables and views data using union all, such as:

<cfquery name="preQry" dbtype="query">

select 'groupA' as Grouping, Item as Desc, sum(fieldCalA) as fielTotal

from tableA

group by Grouping, Desc

union all

select 'groupB' as Grouping, item as Desc, sum(fieldCalA) as fielTotal

from viewB

group by Grouping, Desc

.....

</cfquery>

The data looks like:

GROUP, DESCRIPTION, TOTAL

----------------------------------------------

groupA, ItemA, 10

groupA, ItemB, 25

groupB, ItemC, 30

groupB, ItemD, 20

groupB, ItemE, 50

groupC, itemF, 5

....

How can I add a summary row in my qoq? so my data can be like:

DESCRIPTION, TOTAL

--------------------------------

groupA, 35

   ItemA,10

   ItemB, 25

groupB, 100

  ItemC, 30

  ItemD, 20

  ItemE, 50

groupC, 5

  ItemF, 5

....

Thanks in advance.
