[NTG-context] Endnotes - How to place all endnotes in a separate chapter?

Dear list, How can I collect, in a separate (unnumbered) chapter at the end, or in the Backmatter, of a book, all endnotes from the previous chapters, as lists per chapter (for example in sections in this chapter "Notes", with, preferably, the chaptertitles as sectiontitles of that chapter) My setupfile contains, on the subject of notation, only: \setupnotation[endnote][way=bychapter,bodyfont=10pt] and each chapter now ends with: \placenotes[endnote][height=\textheight] which neatly gives a list at the end of each chapter. Thanks in advance for any advice. Best regards, Robert Blackstone
