On Export, option to export at Medium/Low Graphic Setting

If the graphic option in settings is set to "Low" the shadows from the global light (sun/moon) are not rendered, making rooms unaffected by the global light, but interior lights (torches/lamps) still cast shadows.
Would it be possible to add the option on Export to render at Low Quality to maintain this effect, because at the moment when you render at Low Quality Graphics it defaults to the High Quality image with the global light shadows.
