Function to copy the "Upper value" field values to the "Label" field in the Primary Symbology Graduated Colors Class Pane

When using the Primary symbology pane using graduated colors: It would be neat if the class values within the "Upper value" field within the "Classes" pane could be copied to the Label field within the "More" options.
