This might work if you changed how you labeled things. Instead of using net labels (which won’t show on the finished board), you can change the values of the three “MountingHole_Pad” (though I may have used either THT test points or single pin connectors) to more descriptive values (like SW1C, SW1NO, and SW1NC for Common, NormallyOpen, and NormallyClosed). Then when laying out the board you can show the value in the silkscreen layer. I would also add a SW1 symbol to the schematic with the switches set to include in BOM but exclude from PCB. This would give you full reign to put the three wire footprints anywhere on the board you like.
Just one of many ways to skin this cat.
