foxyproxy

My apologies if this is already possible, but I can't see a way to do this with FoxyProxy as it stands.

I connect to multiple wireless networks, which require different proxy arrangements. At university, I need all external webpages to go through the uni webproxy as specified by a PAC file - internal webpages do not need this and so 'direct connection' can be used for them.

On my home network however, I need all external and internal webpages to go through a 'direct connection', save a select few that need to go through Tor (including those ending in '.onion').

I can set up FoxyProxy to achieve one, but not both of those setups. I get conflicting whitelists because the same URL could be loaded by different proxies depending on the network I'm connected to. The rule for google.com would result in the page being successfully loaded while at uni, but not at home (or vice versa). I want Onion sites routed through Tor at home but blocked completely at uni (ie. sent to the dummy proxy localhost:55555).

Currently I'm having to change proxies manually ("use proxy X for all URLs") as with SwitchProxy etc. If I could change between whole proxy/pattern rule sets, one for university and one for home, then I could make use of FoxyProxy's functionality.
