PF Is there a way to change VPN settings for pf via a web interface?

I'm using VPN on several LAN devices currently. I am interested in trying to set up OpenVPN with my pf nat/firewall box, so LAN devices that need VPN get it automagically with no client software required.

Unfortunately I find that I often need to change my VPN exit point due to speed issues at my VPN provider. With VPN software on each client it is easy to just pick a new exit point and reconnect. Is there a way make a similar quick config change to pf/OpenVPN via a web page on my LAN? Clearly I can do everything at the console, but that isn't going to be easier to use than changing settings at the client... Some kind of web-based VPN control panel for pf/OpenVPN would be ideal. Any ideas?
