Difficulty with Layer name when Exporting to CAD

[dgraue]

When Exporting to CAD, I am having trouble trying to create a layer name for the sill of a window. In Revit the sill (outer and inner) graphically show thinner than the wall's lineweight. The exported dwg file calls this layer (of what should be the "sill") "A-WALL"...the same layer name as the actual wall itself. This line segment is only the width of the window, so it could be changed manually for every instance in CAD from "A-WALL" to say "A-SILL" but come on.

I thought it might be something to do with the window familiy itself, where this window sill area is created by the Opening Cut void, but that doesn't seem to be it because the "A-WALL" layer still shows up below a symbolic sill line. Does anyone have any experience with this?

Thanks.
