When developing a family, it is often mid-project that enhancements may be needed. I often update the origin of a family for convenience when placing further instances. A light fixture may want a center / center origin, but a countertop may be more sensible in a corner so you can place accurately based on wall layouts. When you change which reference planes define the origin of a family and reload, all instances move so the new origin point is in the same spot in the model as the original origin point. This results in families moving to a location you didn't originally place, requiring a subsequent move exercise to fix the previously placed families. I propose an option when loading the family to either move all instances or maintain locations of all instances. Maybe the option based off the major reference planes to account for updates to family geometry as well. Eg: Maintain Front / Center / BACK and LEFT / Center / Right
