Hello, I'm not sure how to do that, but others may be able to help. Before they do I would ask, are you sure you need to make a 5th hardware profile? I too thought I had hardware not covered by the 4 options, but when I oriented the matrix chain with the inputs on the Right and loaded the MD_MAX72XX_HW_Mapper.ino, following the instructions with the panel oriented correctly gave me a different hardware config,
When I had it incorrect, the panel largely worked but with certain weird problems, like reversed order or upside down letters.
Best of luck
