Need filter that displays primary owner and computers.

For our helpdesk people that need to find the owner of the coputer quickly for remote control purposes, before 7.5 SP1 upgrade there was a way to easily type the primary owner in the filter and the computer would display that they were the primary owner.  It seems like this is more of a challenge to figure out under 7.5 SP1.

Here is a query

SELECT
   [vri1_Computer].[Guid] AS [GUID]
FROM
   [vRM_Computer_Item] AS [vri1_Computer]
      LEFT OUTER JOIN [Inv_AeX_AC_Primary_User] AS [dca2_AeX AC Primary User]
         ON ([vri1_Computer].[Guid] = [dca2_AeX AC Primary User].[_ResourceGuid])
      LEFT OUTER JOIN [vAC_IPAddress] AS [ajs3_vAC_IPAddress]
         ON ([vri1_Computer].[Guid] = [ajs3_vAC_IPAddress].[Guid])
      INNER JOIN [vAC_ComputerState] AS [ajs4_vAC_ComputerState]
         ON ([vri1_Computer].[Guid] = [ajs4_vAC_ComputerState].[Guid])
      LEFT OUTER JOIN ([ScopeMembership] AS [ajs5_ScopeMembership]
         LEFT OUTER JOIN [FolderBaseFolder] AS [ajs6_FolderBaseFolder]
            ON ([ajs5_ScopeMembership].[ScopeCollectionGuid] = [ajs6_FolderBaseFolder].[FolderGuid]))
         ON ([vri1_Computer].[Guid] = [ajs5_ScopeMembership].[ResourceGuid])
WHERE
   (
      (
         ([ajs6_FolderBaseFolder].[ParentFolderGuid] = N'91c68fcb-1822-e793-b59c-2684e99a64cd')
         AND
         (LOWER([dca2_AeX AC Primary User].[User]) ='username')
      )
   )

I need a filter that allows adhoc way of pulling up the primary Owner please.  This will only pull up the same user every time.

Thanks.
