We also use V10 for Heritage works and it is very powerful instrument , and used it to produce location maps and drawings with 3D cloud within TBC
we have made stitching outside TBC but for visualization only
Yes there are Pano Stitching software on the Internet that can stitch the one spot photos but you will loose the coordinates and point location, biut leaves the black hole within it
You can also crete an ortho photo in TBC from V10
