Loading multiple pieces (back image)

I am currently working on a La Bataille de Lutzen game.
I know how to upload multiple counter images via “Load Multiple Pieces”. Someone mentioned that there is a way to automagically load the “back” of the counters as well as long as the images are named properly.

For the life of me I can not find any documentation on how this works, any help welcome!


Have you looked through the docs for MassPieceLoader under the Help menu in the Editor?
