There are 4 connectors, each numbered 1-20, within a larger 'cage' that fits in over all 4 connectors. The cage has a whole bunch of mounting holes (some grounded) in non-symmetrical locations that need to fit around the 4 connectors / on top of them. If I build the 4 connectors within 1 part and add them as J1-A, J1-B gates etc, then I could technically name the pins J1-1A, J1-2A, for the first connector, then J1-1B, J1-2B, etc for the 2nd connector, and so on. The problem then is that the pins are numbered J1-1B instead of J1-1, and they all have the same refdes. The 4 connectors need to each have a separate refdes in the part and on the BOM, then the cage is added on the BOM as an item number.
