The SR templates invoked for NUM measurements from TID 2000 do not specifically include finding site, laterality, and topographical modifiers, but these modifiers are not forbidden in the template, they are used in many other NUM value templates (e.g., TID 300 Measurement), and may be present in a SR SOP Instance being transformed to CDA.
