How can I set default option like Line Art in conversion to B&W

I would like to reset the Conversion Method default  to Line Art with Intensity set to 175. How do I do this for every image I open. It is very inefficient for me to have to keep resetting these properties each time I do a conversion from RGB or Grayscale to B&W, and I do a lot of them. Thanks
