Core data - Distinct values

Question

I'm having trouble with core data and fetching distinct values. What I want to do is fetch records that are distinct by one property, but I want to fetch more than one property of a record. If I set setPropertiesToFetch:[NSArray arrayWithObject:@"firstAtrb", @"secondAtrb"] (more than one) then setReturnsDistinctValues:YES returns distinct values by properties defined in setPropertiesToFetch. Is it possible to define a property by which fetch should be distinct but at the same time define more than one property to fetch?
