Adding a field from EcoResAttributeValue to RetailCategory Form

I have created a new enum(noYes) field in EcoResAttributeValue. I want that field to be displayed CategoryAttributesListGrid(Path:Design->MainGroup->DetailTab->CategoryAttributes->CategoryAttributeGroups->CategoryAttributeListGrid) of RetailCategory Form.. Since all datasources are built using query I am finding it difficult to add it.. Can someone help me out??
