[NTG-context] extending \setuparranging[2*4*2]

Willi, following the advice from Hans, I’m asking whether you would be interested in extending \setuparranging. As already explained in previous messages, I think it would be useful to have \setuparranging[2*4*2] for any given number of pages. Having 16 pages to impose isn’t always an option. I read page-imp.mkiv again and I have no idea about how to achieve this. (I found three typos that I attach to this message.) Could you extend \setuparranging[2*4*2] to accept any given number of pages? Many thanks in advance, Pablo -- http://www.ousia.tk
