How to change the DateRange listgrid filter's dateformat

[Sytematic]

I have date and datetime column in various listgrids, and if you click those , you get the popup window where you can select the range. Is it possible to change the dateformat of this to European?

I tried this:

DateRangeItem dateRangeItem = new DateRangeItem("dri", "Date Range");  
dateRangeItem.setAllowRelativeDates(true);
dateRangeItem.setDateFormatter(DateDisplayFormat.TOEUROPEANSHORTDATE);
endDateField.setFilterEditorType(dateRangeItem);

But then the editor is not in a popup, but is put in the header itself, which doesn't fit. So I just want the same popup as now, but then with european date format.

Possible?

(using power edition 2.5, latest nightly)

See all the APIs on DateUtil - you can set formats system-wide instead of in each specific place.
