I'm not aware of any such facility. Basically, it's not really about VPN per se, but per-uid and per-pid routing. I think one could add feature to the routing table to ahve uid/pid in routes and pass those tags into packets from sockets, but it would require a bit of code. Android seems to have this; you can definitely put some programs into a VPN and some not. At least when the VPN is Orbot.
