Capabilities of the custom network protocol macOS

Hi.
I am want to try to create a custom network protocol for a VPN connection, this is my first experience with a task like this, and I can't fully understand the whole capabilities of a custom network protocol.
If the app creates a connection between the system and my VPN server I can block connection from other apps or allow send traffic only for my app through the VPN server.
I ask this because send traffic from the whole system through a VPN server is very expensive for me.

Or maybe exist another way how send traffic only from one app through a VPN or a proxy server?
