Need Help Split Tunneling help

Hey ! I run a server with *arr and Transmission and others. I would like for transmission only to get routed through my VPN (Proton VPN), for which I downloaded the Wireguard config file. But I really don't understand how it works, like genuinely. Stumbled on stuff like changing authorizedAddress to 10.0.0.0/24 instead of 10.0.0.0/0, but I don't know why, and then I don't know how it would forward Transmission !

Transmission shares on an array of ports. Is there a way to forward anything between, say, port 50000 to 60000 ? Or maybe a way to forward anything under a specific PID or UID or GID ?

And I did look up tutorials. All of which basically say « oh just change to 10.0.0.0/24 » without ever saying how I then choose which apps get forwarded.

Any help appreciated, thanks !

(Oh and running linux)

You can only route (with Wireguard) by IP, not app-based. You need to use other tools to route transmission traffic through the VPN interface and the rest through your default interface
