I have purevpn which would be great 8f it worked properly on my Android box. It has a feature called split tunneling that only tunnels for apps I select but the list doesn't show up my iptv app (tivimate) . Does anyone have any other suggestions. I can't use von for all apps as I use direct TV now
I doubt you'll be able to do what you want on Android, however, I split tunnel as you describe on my router.
I made my own custom router using free software called pfsense and you can route specific data to as many different VPNs as you like!
Not exactly the quickest solution to your question, but certainly the most effecient.
Works great to pass torrenting traffic etc through a vpn all while keeping other programs outside the vpn where latency is a concern (ie gaming)
