[NTG-context] Setup of the title of Contents

Hello, I wish I were able to set tup my custom title (for example, for table of contents). I have chapter titles split over two lines and with different sizes so I need something different as a title of Contents. I know about many possibilities of \setuplist options but can't find anything about changing the title style. It seems the basic style is simply derived from the chapter title style. Any advice? Thanks, Honza Hejzl
