Yes, definitely.

Unfortunately there no single variable yet to define that for raster data, too.

This is a cleanup we should do for GRASS GIS 8. I have added it to
https://trac.osgeo.org/grass/wiki/Grass8Planning

Nothing complicated, just a code cleanup is needed here.

As a workaround you could simply replace the location/mapset/.tmp/
with a link to a directory on SSD.
