Showing Stone Veneer in Exterior Elevations for Construction Documents

Ok guys, when generating elevation scenes and exporting to layout and materials you would have added to the exterior are displayed by the style being used for CD Elevations. How or are you guys showing stone, brick or siding when it’s an applied material to your wall? I was thinking of using a color ISO on the sheets containing the flat CD elevations so we can callout materials and colors but printing color is something clients complain about because of the cost. Any ideas or input would be appreciated
