Feature request - a setting to override wi-fi country code

Hi, I have a strong demand in UI setting to override wi-fi country code. My country code in Ropieee is correctly determined as RU, but I cannot access 5Ghz with it at all. Changing country code to US in /etc/wpa_supplicant/wpa_supplicant.conf fixes the issue, and I can even replace get_country_code script. But this all is being reset to RU again on every RoPieee update, which is extremely annoying. Please note that inaccessible 5Ghz on RU is also wrong behavior, we in Russia don’t have this problem with other computer equipment - for example with Apple. So please provide at least a setting to override country code in RoPieee UI

@spockfish Is it possible to add this feature?
