Ok. I'll have to try that from the command line. When using auto-number 
from within the GUI is overwrites instantations of slots which it shouldn't.

Yes, that is a problem because renumbering is typically done after 
placement or at the end of a layout. It makes board repairs a lot easier 
for the techs. However, for PADS (which my layouter uses) I have found this:
