Hmm had to think abit about your question.

Maybe try this.  Locate 1 of the images that contains your point of interest.  Load this 1 image into PW and tell it to stitch.  What it will probably do is "You can't do that here - not enough images to stitch".  Push the stitch button anyway and see if it will dewarp your 1 image.

I know there is other stitching software that will stitch (dewarp) 1 image.
