Creating section/elevaion marker that one side can be different from the other can be done using "SYMB_MIRRORED". But when the section/elevation is set to "Marker Head in the Middle", Archicad draws the marker wih either SYMB_MIRRORED or not(SYMB_MIRRORED), not both. So, it'd be great for the GDL section/elevation marker to "know" which option is selected so the script could react accordingly.
