Route rclone traffic through vpn

Is it possible to selectively route rclone network traffic through a VPN?

You can use --bind command to select what interface to use.

yes, i do that all the time,

when you connect to the vpn, if your default route is over the vpn, then you do not need --bind.
you can do this command and see what your defaute route is.
