I created a mod. Short story, it let's you set a specific (custom) uniform per region quickly and easily. I haven't published it on LSPDFR yet because I'm looking for feedback from the BETA version. If you'd like to test my mod you can download the zip here: https://github.com/th0547/EUPRegions/tree/main Or you can download, I attached the ZIP file. Please read the readme first, there's also a technical description to give a more in depth view of how this mod works. I'd be very happy to hear what you guys think. There are a few bugs (nothing too bad) but please let me know if you find anything, it would really help me improve this mod!
