How to copy paste footprint in layout and re-assign components

[Qbort]

Right now you can copy/paste the two sections in the PCB and then manually rename the designators to make them match the schematic. Have a look at this post below:

Update PCB from Schematic's match methods

Updating an existing layout from its schematic requires KiCad to determine which footprint was previously connected to which symbol to avoid undoing your past work. For this reason every symbol is assigned a unique identifier (timestamp based unique ID). This ID is also tracked by the footprint instance. The alternative option is to use the reference designator assigned to your symbol either by the annotation process or by hand. Using the ID allows, changing the reference designator of a symbol…
