PIA VPN allow 1 program though?

[squirrellydw]

So I have PIA VPN setup on my router and it works great. I also have it configured to allow some devices through the WAN and not go through the VPN.

My question is I currently have my server going through the VPN but by doing this I can't access Plex. PIA doesn't support port forwarding on all their servers. Is there any way that I can allow just Plex to go through the WAN and everything else through the VPN?

If not I can just have the server go through the WAN like it was before I had the VPN
