Yes there is a "PTOT.vmdx" file that is available since at least 2018. It's simply the PTO chart cheat sheet that Mark Pitcavage had on his DM site. Where I picked it up? Unknown, but perhaps the Texas ASL site.
This is a good hint, thanks.
I did not find it neither on the Texas ASL site nor on Desperation Morale, though. Google doesn't know it either.
I reckon, some Japanese Halfsquad snatched it and craftily gained Concealment at the end of the next CCPh, never to be seen again...
A suggestion:
If you have the extension, you could forward it to the guys at vasl.info, who could then add it to the list of extensions on their site.
