There’s no nice way to do this I think. All I can currently suggest is to include the device into the network, let it create the XML, and then edit the XML to set it to 0004:0004. This should work so long as the XML doesn’t get deleted (which can happen if there are changes to the binding that impact the format).
The other option (maybe!) is to send the incorrect ones back to Popp and ask them to replace them with ones that are correctly defined, as per their own statement above ;).
