I like this, although it's not so terribly difficult to get the same effect with a little planning. Sometimes the design drags you away from the plan ;-)

Yes, for reasons Kai-Martin said. This shouldn't be too difficult to fix, since you've already managed to penetrate the obscure code here (good job!). There must be somewhere that the offset of the symbol within the schematic is stored (it's needed to generate the "C" record in the schematic file). Subtract that from the coordinates in the instance to make a proper sym file.
