Dual WAN, route Plex/Jellyfin traffic through second WAN

[Offspring]

I've got a Dual WAN setup, where both connections are available and seen. I've got the primary one set as the default for everything, but I'd like to route all Plex and Jellyfin traffic through the secondary WAN connection. What would the steps for that be?

Everything for Plex goes over 32400, and Jellyfin is 8920. Thanks in advance for this.
