There is no easy way of doing this now but it sounds like we need an
option in the "edit spectrum reference" popup which says "do you want peak
positions fixed in points or ppm?" (is there any other alternative?).
Since the positions are stored in points the "ppm" option would involve
having to iterate over all the peaks updating the information, but that's
not the end of the world.
