Split tunneling applications?

[zoochosis 0]

Is there a way to easily 'split tunnel' applications with airvpn? I'm a previous user of Mullvad VPN, and split tunneling was a feature I used often for steam and plex. I know there's a way to remove specific IP addresses from the VPN with airvpn, but I'm not sure where to start with that to fix my issues. I'm looking to do this for Android and Linux. (I'm only functionally literate in the latter, so forgive me if I'm using some terms incorrectly in this post! 😓)
Alternatively, if excluding applications from traffic is not possible, is there a way to limit it to specific applications (firefox?)

Android is straightforward, just exclude the Steam app in the Eddie app.
In Eddie for PC traffic splitting is only possible by IP and ranges. On Linux, though, you can use the AirVPN suite in concert with Cuckoo, Air's traffic spitting manager, but it's CLI only for now.
