Change Coordinate Widget seperator to point

[Wasserwiki]

I have a custom Web App build with the WAB. It's default language is german.

Now if I use the coordinate widget, coordiantes are sperated with a comma(Comma is the german default sperator). This is very impracitcal.

Is there a way to change the seperator to a point without changing the default language - maybe in the files of the web app?
