Creating localized network home

Is there anyone who know how creating a network users in Workgroup Manager chosing a network home localized with a language other than english?

I cannot change /System/Library/User\ Template/English.lproj and in the Mac OS X Server is localized only in 4 languages.
I saw also that if I let user creating his/her network home folder the first time he/she make login ( because of AFP Network Mount Point), the home didn’t follow the localization of the first user who installed that Mac OS X Client.

So, please, any ideas would be appreciated!!

Cheers
