I have been working for several months to incorporate RenumKicadPCB functionality inside Kicad. Meanwhile, Alexander Shuklin has done most of the heavy lifting by writing back-annotation into Kicad which does all of the error checking, etc., necessary for reannotation to work. Without his help I don’t think I could have done this.
Geographical re-annotation is under PCBNew/Tools. It should provide the same functionality as RenumKicadPCB but from within Kicad. I am hopeful I can submit a merge request which will be accepted so it will become part of the distribution. Of course, given my modest c++ skills I suspect that will not go smoothly!
I have tested the code with all the projects I used to test RenumKicadPCB and it appears to work. Besides renumbering correctly, it seems to detect project errors such as modules in the PCB which are not in the schematic, etc.
I would be grateful if people who are interested in this functionality would help test it and let me know if they have any problems or suggestions.
