For now it is considered as a custom code modification of the plugin, You are free to do that on your own or hire a programmer to do that for you. You can do that here: http://www.oxwall.org/market/specialists
Soon 1 year have gone , when will you follow you own core? it suppots only half of the software and we are in 2017 soon and update 1.8.5 soon. This plugin is OLD and should not have the numbers 1.8.4 ...fake marketing
A free advice....use cloudflare and they google analytic app that is free to download at cloudflares app section. works much better when it comes to pagespeed insight tool and support everything....
this plugin is old stuff and get problem with many speed tools and this developers blame it on google but i think there is fixes for everything because i not have such issues with cloudflares google analytic plugin
