[NTG-context] extended dictionary / hyphenation patterns

Hi, I guess German is famous for its monstrous compound words ;o( So I have a manually collected lists of hyphenation patterns (like "\hyphenation{Selbst-kon-troll-ein-rich-tung}"). This I'd like to keep as a two separate files: on for usage with the body-text set in \mainlanguage[deo] and one for \mainlanguage[de]. Is there a handy way to automatically assign and include one of these files (HyPold and HyPnew) to the usage of the respective \mainlanguage [deo] and [de] ? Steffen
