[NTG-context] direction in columnset (MKII)

Hi all, Is it possible to tell columnsets which column is the first one? I use columnset in MKII to typeset Arabic text in a multicolumn layout and the text starts in the left column. Is there a nice way to force the text to start in the right column? Something like \definecolumnset[arabic][n=2,direction=right] doesn't work. (A nasty, ugly hack is fine too ;-) Example: \starttext \definecolumnset[arabic][n=2,direction=right] \startcolumns[arabic] Oeps. In Arabic the 'first' column is on the right: \input knuth \stopcolumns \stoptext Thanks, Jelle
