What would the snippet(s) look like for multiple google analytics tracking IDs? I'd like to include 3 tracking IDs on all pages. I'm using the Google Analytics module and there are three fields in the custom javascript code under advanced settings.
Using Universal Google Analytics, in the Google Analytics Module 7.x-2.0 @ /admin/config/system/googleanalytics > ADVANCED SETTINGS > CUSTOM JAVASCRIPT CODE > Code snippet (after)

ga('create', 'UA-XXXXXXXX-Y', 'auto', {'name': 'foo'});
ga(function(foo) {
  foo.send('pageview');
});
ga('create', 'UA-XXXXXXXX-Y', 'auto', {'name': 'bar'});
ga(function(bar) {
  bar.send('pageview');
});
