Switch Proxy based on Machine's IP Address

Thanks for your excellent add-on. It works great for most places that I browse the internet.
The problem I have is that every time I connect from a different location, I have to select a different proxy from the menu.

I wanted to know if you could include a feature to select a different proxy automatically based on the computer's IP address, similar to the way the IP address changes based on the [black|white]list specified by the user.

This feature is available

This feature is available for FoxyProxy Plus users - it's called Local IP Address Pattern - enables different proxies based on your local IP address (only Windows supported).
