I would like to know if there is any way to create a symbol that contains more pins in the schematic than pads in the pcb. In my case, I designed the connections of the bms with the LiPo, but this circuit boils down to a connector KK that will receive the output of the BMS. Below are the images of the symbol, the schematic and the error.
Welcome ! out of your 2 options I would go with number 2. It honestly would be just a few minutes to create a symbol that suits the purpose and have no pesky errors ! but that’s just me
