I too would like this functionality!  I am dealing
with meshes with over 60,000 elements and am in
the process of converting to hexahedra where
possible.  Recent studies of mine have suggested
that the hexahedra are more efficient than the
tetrahedra due to the shape functions crossing the
boundaries of the tetrahedra used to make up the
hexahedral volumes not being continuous.  My
tetrahedra meshes require smaller elements than my
hexahedra meshes, for the same accuracy.


Best regards,

Mark.
