Make the UTM tag links short and pretty

[metmarkosaric]

"I have always found that utm tracking creates long and ugly URLs. Have you considered a feature to allow utm tracking to be hidden using a hash fragment? I think that would be a killer feature, and currently the way to administer it via google tag manager looks really cumbersome, I think you could create a much more streamlined UI which would be a good differentiator from GA."

Instructions here on how it is done using Google Tag Manager and Google Analytics: https://www.getelevar.com/how-to/hide-google-utm-parameters-from-url/
