[NTG-context] A page for figures ?

Hi all, I would reserve a page for several figure (i.e. \placefigure). \placefigure[page] reserve ONE page for ONE figure... Can \placefigure reserve a page for several figures with an option I don't know yet ??? Since I assume \placefigure can do that for me, I don't want to use \placefigure[page]{none}{\startcombination...\stopcombination}... ;) TIA Renaud
