Hi Manuel, 

We’re currently evaluating ways we can improve our reporting and analytics functionality; we’re hoping to give this an update in 2015. At the moment, your best option would be to simply use Google Analytics for all of your detailed and historical tracking for now. We make it super easy to embed Google Analytics into your pages by using our Script Manager tool, and you can find out how to integrate G/A into your landing pages here. 

Thanks for the feedback though! If you, or anyone else has more suggestions on what you would like to see in future versions of reporting, please sound off in the comments below.
