Auto hatch faces made by split line?

Hi everyone,

I often times apply a split line to shafts or other surfaces to add laser marking to a part. In the drawing, I go in and put a solid hatch mark to fill in the faces. This can be pretty tedious with all of the drawings I have, so I was wondering if there is any way to auto select the faces created by the split line operation and hatch mark them on my drawing in a one click sort of operation? I would be fine with exploring macro options, but I'm unsure how to select the associated faces from the split line operation (which is the part that is actually tedious).

Thanks!
