BOMS, CONFIGURATIONS

I have an assembly that has a switch box in it. This switchbox has 4 configurations for the various starters used in the box(box itself is the same). I have an assembly with bom calling outthe box plus fittings. What I would like to do is list all 4configs in the bom, but can only seem to list the current one usedin the asm. I can manually do it but fear that a rev (somewhereanywhere) will create havoc in the future.SolidworksBill Of Materials
