how to manage Word layout based on condition

hello,
Actually we can manage different Word layouts per customer.

Did anybody try to get same effect but based on a customer group or language code or something more "global".
I want NAV to choose a Word layout based on a language code for example. So I can store my different Word layouts behind one single report in different languages and when printing, the system chooses the right one based on customer language code.

thanx for any inputs.
