Don't know if it is the least work option.

I however got around this by drawing 4 pins on the
switch.  Connecting the common ones in the schematic.
Finally putting in a fake copper layer in PCB with a
small copper shunt between the commons.

I guess the danger in that one is that someone in
the future that doesn't realise why might make a
three (four) layer PCB when it is not needed.
