Restricting portal UWL for selected SAP Inbox enteries

Hi,

I want to restrict my portal UWL for selected enteries of SAP Inbox, which means if SAP Inbox is having 10 enteries , I want only selected enteries should be visible in my UWL, what is happening now is all the sap INbox is appearing in my portal UWL.

I want to restrict my portal UWL for the ESS/MSS work item only, all other things should not be visible to my portal UWL.
