It would be great if you could add a wall reveal material line item to the wall type such as a wall base reveal or be able to paint it separately or change the material without having to take the time create split regions. This way you could have a different color wall base in different rooms, without having to create a separate wall types, or taking the time to put in wall sweeps or having to add separate reveals from the wall. This way it's part of the wall type but able to change colors/materials. this would also be good if it worked for revels for crown moldings at ceilings or chair rails. This way it would be part of the wall.
