Yes, we can make that way that you get smaller regions instead of the larger ones. Let's keep both options possible, so you would place poly files under hierarchy folder in GitHub. Poly files are used when I generate the regions, not on device. So, you would have to make it in GitHub and send over to me via forking/pull request in GitHub. Then I can run scripts on my computer, send it to @MartinK system and download them to your phone. Easy, isn't it
