You could write a proxy.pac autoconfiguration containing something like:

if (isInNet(myIpAddress(), "192.168.1.0", "255.255.255.0"))
        return "PROXY proxy-for-net-1";
if (isInNet(myIpAddress(), "192.168.2.0", "255.255.255.0"))
        return "PROXY proxy-for-net-2";
...
// in none of the nets we know a proxy for:
return "DIRECT";

You could also set up WPAD, the Web Proxy Auto Discovery protocol,
in each office so that clients will automatically pick up a different
proxy.pac script depending on the office they are in. Or you could
define a DNS alias that resolves differently on the different offices'
DNS servers. But I think I'd prefer the proxy.pac script solution.
