[NTG-context] itemize textstyle

Hi all, is it possible to assign different styles to each itemgroup or level of 'itemization'? It is possible when using \head to assign a headstyle, but wouldn't it be nice to assign a certain textstyle to an item level? Consider something heavily customized (but still useful IMHO) like this: 1. First Level (bold, small caps) - Second level (normal) > third level (italic) * fourth level (smaller font [\tfx], text color dark gray) I somehow can't find a way to achieve this, without applying the style in the actual list. I also do not know what these before and after keys do, but I assume they control more the surroundings than being a command that is insterted "before" and "after" the item text. Best Regards!
