Option to turn off specular on directional lights/sun

I’d love if I was able to turn off specular lights for directional lighting. Directional lights act like the sun and leave a big glowing ball when used. It would be great to be able to disable this if using multiple directional lights. It would also be helpful to be have access to turn this off on the sun as well. Specular lighting options are only available on certain type of light entities.
