Hello, If I were to delete a component and replace this component in my schematic, for example delete a polar capacitor and replace it with a nonpolar (different schematic symbol) when I import my changes into the PCB that component will be moved off the board and to the bottom right.  This means that I have to reorient, correct the layer and re place the new component.  This combined with the fact that the "assign part number" in the BOM button does not fully update the existing parts parts is not convenient.  It would be much better if importing the new parts into the PCB simply updated the parts footprint/info in the same location as is was. Or if the assign part number function of the BOM updated the parts info completely in the schematic. Thank You.
