Create a Query with Defaultset where I can pass data dynamically

Hi guys,

I want a feature like My Accounts in one of my OWL but where can I pass DYNAMIC data ( for exapmple current user's uuid or something).

I have created OWL for my xbo of my account and i am already passing a static value in a field . please refer below screen shot

Now as I want similar functionalit y just as My accouns I have added Employee resposible in one of the parameter in query. pllease refer below screen shot.

now i have created another default set but i dont think so we can dynamically pass Current user's id or uuid into that... So that i can achive similar functionality as My Account..

any one can guide on that thanks in advanced
