Try using the Type Mark parameter, already built in, instead of creating a new parameter. You'll need to populate it however, so it's still a workaround. I found that if it's a category for which you don't use Type Mark for annotations, Revit will allow multiple types to use the same Type Mark (but it will give you a warning), which might simplify filtering
