BI 4.0: Set language for group of users in CMC

Hello,

in BO 3.1 it was possible to set the preferences (and language) with job prefsUtilCopy.jar. This is not supported any more with BI 4.0.

In BI 4.0 administrators can save default preferences at the User Group level in CMC but only for small set of preferences (not language).

Is there possibility to change language for group of users in BI 4.0?

Thanks
