No convenient way to swap different proxies?

Pseudoryx

I have two active proxies and was trying to jump between them to test which one already has access to a library. Before the link was proxied, there was a clear menu item to pick between the two proxies, but after I picked one there does not seem to be an intuitive way to disable the proxy redirection or switch to the other proxy at all. Is it just a nonexistent feature?
