Use zoho.loginuser in embedded Zoho Reports table or dashboard element?

Hello - 
As the title describes, I am trying to determine if I can filter an embedded table or dashboard element on a user basis, by applying the  zoho.loginuser system variable. I would like to create an embedded table or dashboard element that filters data based upon the user that is currently logged into Zoho CRM/Reports. But - I cannot seem to apply (column =  zoho.loginuser) when applying Filter Criteria. Any pointers as to how I can make this work?
