I would like to see that, too. But it's not yet implemented...

Meanwhile, you could use the GDAL tools directly on the GRASS location
using the GRASS-GDAL plugin:
http://grass.osgeo.org/wiki/Compile_and_install_GRASS_and_QGIS_with_GDAL/OGR_Plugin#Usage_of_the_plugin

Through this GDAL sees GRASS maps like maps in other formats
and you could create the map stack from there.
