Need to create a report on pending tickets where last reply by requester

Hello,

I need to produce a report of all pending tickets where the last conversation was by the requester along with the date and time they replied (i.e. technician has not yet replied to the requester). I have an existing tabular report filtered where 'Last reply' is 'REQ_REPLY', but it doesn't list or have an option to show the date/time of the requesters reply. It does show Last Update Time, but that could relate to anything. Running on MSSQL database. SQL for the existing report below

SELECT "qd"."QUEUENAME" AS "Group", "wo"."WORKORDERID" AS "Request ID", "serdef"."NAME" AS "Service Category", "aau"."FIRST_NAME" AS "Requester", "wo"."TITLE" AS "Subject", "qd"."QUEUENAME" AS "Group", "ti"."FIRST_NAME" AS "Technician", "std"."STATUSNAME" AS "Request Status", "wo"."CREATEDTIME" AS "Created Time", "wo"."DUEBYTIME" AS "DueBy Time", "wos"."ISOVERDUE" AS "Overdue Status", "wos"."LAST_TECH_UPDATE" AS "Last Update Time" FROM "WorkOrder" "wo" LEFT JOIN "SDUser" "sdu" ON "wo"."REQUESTERID"="sdu"."USERID" LEFT JOIN "AaaUser" "aau" ON "sdu"."USERID"="aau"."USER_ID" LEFT JOIN "ServiceDefinition" "serdef" ON "wo"."SERVICEID"="serdef"."SERVICEID" LEFT JOIN "WorkOrderStates" "wos" ON "wo"."WORKORDERID"="wos"."WORKORDERID" LEFT JOIN "SDUser" "td" ON "wos"."OWNERID"="td"."USERID" LEFT JOIN "AaaUser" "ti" ON "td"."USERID"="ti"."USER_ID" LEFT JOIN "StatusDefinition" "std" ON "wos"."STATUSID"="std"."STATUSID" LEFT JOIN "WorkOrder_Queue" "woq" ON "wo"."WORKORDERID"="woq"."WORKORDERID" LEFT JOIN "QueueDefinition" "qd" ON "woq"."QUEUEID"="qd"."QUEUEID" WHERE ( ( ( ( "serdef"."NAME" = N'Incident' ) OR ( "serdef"."NAME" = N'Service Request' ) ) AND ( ( ( ( "std"."STATUSNAME" = N'Assigned' ) OR ( "std"."STATUSNAME" = N'In-Progress' ) ) OR ( "std"."STATUSNAME" = N'Onhold' ) ) OR ( "std"."STATUSNAME" = N'Open' ) ) ) AND ( "wos"."NOTIFICATIONSTATUS" = N'REQ_REPLY' ) ) AND wo.ISPARENT='1' ORDER BY 1, 12
