Actually I was thinking of deleting them from the file to make it
smaller. The only problem is remembering which ones were deleted and
which ones are new at update time. I'm not sure how to automate
additions either way. Probably have to use the sorted properties of
parts.lst

I think that makes sense. Apply the mirror transform and/or substitution
from MIRROR.INI individually to all parts in the subfile, then apply a
global mirror (across whatever axis you want) to the whole subfile.
It sounds so simple. Could it be?
