Autoballoons with custom properties

I have an assembly with parts that have custom properties.I'm calling out these custom properties in the drawing with theauto balloon button. The problem is that only some of the partshave the custom property I'm calling out, and I don't want balloonson the parts that do not have this property. Is it possible to tellSolidWorks to auto balloon the parts that have custom property "X"and ignore the parts that don't have custom property "X"?

I've just been deleting all the empty balloons that I get, but I'dlike to not have the empty balloons in the first place.SolidworksDrawings And Detailing
