Ressurecting an old post because I found it very helpful.
One thing I want to add that was not apparent from the help file was that the TERMx value has to be on the footprint for the other added attributes to work. I initially added only the WIRENOx attribute to the footprint and it was not updating until I added the TERMx att. Since I do not want to have the TERMx info displayed, I just hid it in the footprint and everything works like a Charm.
Also the associated att has to exist in the schematic symbol; i.e. I wanted the wire number of a distribution block to appear on the footprint so I had to add WIRENO01 to the schematic symbol and TERM01 and WIRENO01 to the footprint symbol.
Thanks again Pat!!
