Localization numeric formatting (periods and commas)

In the Netherlands, as well as a lot of other countries, we use commas to indicate the decimal place. We also use periods to seperate thousands, but only for currencies.

I have a PowerPivot datasource in which formatting is correctly displayed. However Power BI graphics (e.g.: Table and Card) always seem to display numbers in US/UK format, independent of browser settings. Can I change this somehow, or is this not possible yet?
