See this Comm Center post by Bruce McMath.
On another item, it sure would be nice if a new image set within a plan would come already filled in with the data from the first image set. Something obviously would have to be altered but most of the time the coordinates and a few other items will be the same.
I'm right there with him on this. I have exported an image set then repeatedly imported it in order to add more that are similar (different filter only or whatever).
The right way: Add Duplicate logic for Plan, Observation, and ImageSet.
