How to change region efficiently with a VPN?

I checked a lot of reddit posts about VPN & Valorant but did not find an answer to my quesiton. My question is mostly for people using VPN (I use Nord VPN) Context: I'm in Canada and my friend is in Europe so to play together I play in EU servers. Without VPN I'm around 120 to 210ms ping, depending on what server we play on. When I use a VPN, if we play in Frankfurt for example, I set myself to frankfurt and I can get 90 or 89ms ping. or 90 in London, or 90/100 in Paris etc.... (each country I have to change my VPN location to optimize the ping) We usually play in Frankfurt but it looks like Valorant doesn't detect the VPN sometimes, what I do is: I launch the game when I see the main menu screen I open the VPN and connect to Frankfurt and then wait few minutes for valorant to connect to it and it works like 1 out 5 or 8 times, I repeat the process until it works before we play (I tried to change the location before loading the game but it works rarely too) My Nord VPN is set up with split tunneling (using VPN for specific apps only, see photo) Question: Do someone have a better way to set up the VPN without trying a million times before having a decent ping in the server we play in ? I just know that it can go to 90 pin I just don't want to try 10 times every time we play
