What you need to do when stacking parts is to use the combine option.
This will make the software think that you are looking at 1 stl file. When
are created on the combined parts instead of the supports building through
you will now have sierras on both the top and bottom of the supports.
The upper and bottom surface finish will now be the same.
Hope that this is of help
