[NTG-context] Help with citation layout.

Dear list, I need the help of a BibTeX/citation module expert. I want to modify the appearance of @INBOOK entries. Currently they look like this (apa-de style): author (year) _booktitle_, Chapter chaptertitle, pages, publisher, edition. What I'm aming for is this: author (year) _chaptertitle_, In editor (Edt.): _booktitle_, pages, publisher, edition. Where chaptertitle refers to the title of the chapter (usually some sort of article or essay), very similar to arttitle. Is there a way to accomplish this? Or is the INBOOK entry not meant to do this? I'm especially having trouble to get the editor to show up (let alone having "In " in front of it). Does editor and author conflict here? Thank you for you help!
