forward panorama to InPaint for further processing

Teorex makes good software, and I loved Inpaint when I had it on my previous PC.

I would like PhotoStitcher to "forward" the panorama file (while it is still being processed, and has not yet been saved) to another Teorex software like Inpaint, so that I can manipulate the photo further before saving it. Thus, there will be less concerns of losing image quality through cycles of jpg compression, and there will be an more streamlined experience when working with Teorex family products.
