Is there way to switch between proxy settings on ICS?

I have an Xperia S running 4.0.4. I often need to switch to a proxy for accessing a test server. I can do this fine by modifying my Wifi connection, selecting to show advanced options and then entering the proxy information manually. The problem is that if I then need to disable the proxy, ICS 'forgets' the settings so I have to enter them manually each time. I need the proxy to work with Adobe Edge Inspect and so browser-specific proxy options are not the answer. Is there a reputable third-party app which will let me switch between proxies for the current network connection?
