[NTG-context] startMPpage..stopMPpage written to a separate PDF?

[Gerben Wierda]

I have a series of startMPpage—stopMPpage pairs (with MP code inbetween). These now become separate pages in a single PDF. But I need them to become separate PDF’s each during my ConTeXt run, with a name of my own choosing. Is this possible? I guess this will be problematic, but one can hope (maybe some very low level TeX trickery)...

Thanks,

G
