Stan, I added the jumper field to solve any cutting issue. That allows me to build the board with both capabilities and just jumper it for the desired operation.
There's a little fooling around to try to graft components in that aren't in the design. I suppose it could be done, but I'm not sure how much effort it would be. I think the way to do the resistor substitution would likely be just change the 3D file to a resistor and then try to position it.
