I wish that in the Material definitions in the styles of a part you could assign a hatch pattern to use for that material. You can assign a colour style to use for visualization, a hatch style would be nice for use in drawings.
When I hatch a part or assembly view it could then automatically use the hatch that's in the Hatch Style. Thus if I have a steel column protruding from a concrete block when I create a break out view or other I get different hatches for the different materials.
