Need Two SUMS In Pivot Table

I currently have a pivot table query that is working great but I need to add to it. The below code is giving me the total ServiceTime per date. I need to split this service time out depending on the stage of this note. Basically I need to pivot table queries and join them together.

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 and the dates are dynamic.

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]
