Using Two SUM Columns In A Pivot Table

I currently have a pivot table that is working great but I need to add to it. The below code is giving me the total ServiceTime per date, which is dynamic. I need to split this service time out depending on the stage of this note.

1) If the note has been signed
2) If the note has been signed and countersigned

SUM(CASE WHEN countersigned_id IS NULL AND signed_id IS NOT NULL THEN ISNULL(d.time_face, 0) + ISNULL(d.time_other, 0) ELSE
0 END) as PendingServiceTime,

SUM(CASE WHEN countersigned_id IS NOT NULL THEN ISNULL(d.time_face, 0) + ISNULL(d.time_other, 0) ELSE
0 END) as ApprovedServiceTime

How do I add this to my pivot table query? I am thinking that I need to have two seperate queries and join them together some how.


SELECT lastname + ', ' + firstname as FullName, [12/3/2007], [12/4/2007], [12/5/2007]
FROM (SELECT p.LastName, p.FirstName, t.ServiceDate,

ISNULL(d.time_face, 0) + ISNULL(d.time_other, 0) AS ServiceTime

FROM dbo.allNotes(8) AS t
LEFT JOIN dbo.note_Collateral_provider AS d ON d.note_Collateral_id = t.ID
LEFT JOIN dbo.Personnel as p ON d.personnel_id = p.ID
LEFT JOIN dbo.Clients as c on t.ClientID = c.ID
LEFT JOIN fPayor(8) fp on fp.noteId = t.id and fp.dbTable = 'collateral'
LEFT JOIN dbo.payor py ON py.ID = substring(fp.fPayorName, 41, 19)
LEFT JOIN dbo.payorinfo pyInfo ON pyInfo.ID = py.payorinfoid
WHERE t.AgencyID = 8 AND t.tableName = 'collateral'
AND t.not_billable_reason_id IS NULL AND VOID_ID IS NULL
AND ((t.signed_id IS NOT NULL AND t.countersigned_id IS NULL) OR (t.countersigned_id IS NOT NULL))
AND t.ServiceDate BETWEEN CONVERT(DATETIME, '12/03/2007') AND CONVERT(DATETIME, '12/05/2007')
) rs Pivot (SUM(rs.ServiceTime) FOR rs.ServiceDate IN ([12/3/2007], [12/4/2007], [12/5/2007]
