Date Format Problem with Streaming Data Set

Having a pbi streaming data set (with history) with a column of type datetime (filled by a stream analytics output). Power BI Portal Language is set to "German". But display in pbi report table is still in format: mm/dd/yyyy. What I need is: dd/mm/yyyy. I don't see any possiblity get the desired date format based on a streaming dataset? (Content in the colum of the datetime looks like: "2016-12-05T16:27:27.926Z") To be able to set a locale in a Report or Dashboard like in SSRS would be handy but any other solution to the described problem is very welcome!
