Plate Solve off-telescope

I may have missed it in the manual but is there a way to plate solve an existing image? I’ve been using astrometry.net successfully but now that clouds (and snow) have been predicted for the next week or more, I’d like to try the other methods on an existing image. Any way to do this?

File/Open Image then right click on the image and select Plate Solve.

Tnx, I knew it had to be there somewhere!
