Voyager's Drag Script interface can be used to automate this and your imaging session, flats session, and ending processes in one script.

Ray added the ability to call and start APPM from the command line, which would be used in this case by Drag Script.

As I think you know, automation is not 100% reliable. Since you would be at a dark site, the value of good imaging results will be important, so I would be surprised if you didn't want to check progress occasionally!

But let's think this through. Say that APPM could be automated. That wouldn't prevent APPM from getting hung up on a bad plate-solve or other error. How would you detect this and delay your automated imaging session?

Understood, and thanks for posting your idea. I have put it on my list of potential future features.
