impossible to import files for split tunneling
as written here: https://ask.fedoraproject.org/en/question/124166/network-manager-openvpn-plugin-not-importing-correctly-ovpn-configuration/ this seems impossible to do https://www.mullvad.net/fr/guides/split-tunneling-mullvad-vpn/ your plugin doesn't accept it because there is no gateways for those routes. Those gateways are acquired afterwards, while connecting. your plugin doesn't accept that. Openvpn does accept it because it works like a charm in CLI and in windows.
