Thanks for your feedback – we’re evaluating options on how we can include this functionality in an upcoming release.Paulo commented
I can't believe this wasn't included in the August 2018 release! This is absolutely required!
We’ve begun work on this feature and a few others related to the export and subscription scenarios you have been looking for updates around. In addition to keeping you updated on the progress here, a blog post I’m posting on the Power BI blog next week will provide a look at what’s happening now and in the next few months in these areas.
