**Concise problem statement**: for manual soldering, I often increase the pad sizes on the PCB to make this easier. When then updating the PCB with e.g. a pin-remapping from the schematics, all such modifications are lost.
Steps to reproduce bug:
1. Add Schematic with pads for through hole components
2. Change the width/height of the pads
3. Add new component to schematic, and use Update PCB
Results: The pads are all reset
Expected results: Settings that can only be configured on the PCB, and not in the Schematic, are left alone
