Option to only use data connection, when connected to specific Wifi.

The reason for this being that my college's network seems to block the google messages API, so the app can't update on my laptop, if i'm on my college wifi, so it would be nice to be able to blacklist that wifi, so that if I am on it, the app will use data, instead of wifi for that wifi network only, so I don't have to turn on and off my wifi based on my location.
