Scripting openvpn client changes

[SchuFire]

Please forgive the seemingly noob question....

Running pfSense CE 2.7.2

I have 10 openvpn clients configured. I would like to automate rotating through those 10 clients through a cron job.

As it stands right now, I have to perform the following manually.

1. Navigate to interfaces -- interface assignments -- use the network port drop down for my OPT1 interface to change to the desired openvpn client
2. Navigate to VPN -- openvpn -- clients -- edit the currently active client and check the disabled (disable this client) checkbox -- save
3. From VPN -- openvpn -- clients -- edit the desired client and UNcheck the disabled (disable this client) checkbox -- save

As expected the VPN egress changes to the location defined in the newly enabled openvpn client. This process works fine but is manual. I looed at the documentation (no help at all), found some github sites that came sorta close, and played around with the shell and PHP shell options but with no euccess

I welcome any thoughts or ideas.

Many thanks.
