Variants seem to be defined as present or not present.
Is there a variant that can assign different parts to the same reference designator? i.e. R17 can be either 0 ohm 0805 jumper or 12k ohms 0805 resistor.
The simplest way I can think of is to use two parts with the same footprint and overlay them.
Is there a more functional way of doing this? So that the variant would put the correct part in the BOM and the parts would of course have the same identical footprint.
