BIRT with Maximo Possible to design lookup if parameter is not bound to an attribute (if so how?)

I am working with BIRT and Maximo. I need to add a lookup to a parameter, however the parameter is NOT bound to an attribute. (there are say four values I would like to have appear: OJS BIA BIE SDCP for example). I see there are some OOB parameters NOT bound to an attribute that have a yornlookuplist associated with them so I know it is technically possible but I am not sure how to do it. I am using Maximo btw with the 431 BIRT designer ide. Can someone point me to how to do this or detail the process?
