[dune-pdelab] Question on space construction

Dear pdelab team,
I have a question concerning the tree construction of FE spaces in pdelab.
In my problem, I have two P1 FE spaces. One is 3-valued, and the other one
is 5-valued. What I want is the product space of the two, so I guess I should
use the CompositeGridFunctionSpace class. However, I also want the resulting
stiffness matrix to be BCRSMatrix<FieldMatrix<double,8,8> >.
How do I do this? Is this combination of blocking across a CompositeGFSpace
possible at all?
Thanks for your help,
