(any possibility to avoid additional data copy?)

I need ability to copy back to host memory only one array from 2D-table.
AFAIK it should be possible by using stream domain. But this would involve additional data copy inside GPU memory.
Is any way exist to write part of 2D stream back to host memory w/o any additional data copying?
