[NTG-context] Imposition and repeating pages

Hi, imposition in ConTeXt is great, but... 1. When I last used it (MkII), I had to invoke texexec with the --arrange option or something like this. Does it work in an easier way with MkIV? (I mean, I just do context filename and don't care about multiple runs etc.) 2. I'd like to prepare a cheat sheet of size, say, A6, so I want *the same page* to be repeated 4 times on an A4 sheet. Is there a "canonical" way to do it? (I mean, other than copying-and-pasting, or equivalently, defining a macro and repeating it 4 times?) TIA -- Marcin Borkowski
