I think the closest thing (or maybe the easiest) for doing that is changing the value of the variable called epsilon-input-file with the following instruction (set! epsilon-input-file "SomeHDF5FileName"). With this you can specify the default material, and thus the matrix you are referring by generating externally an HDF5 file. Unfortunately you can only specify the effective permitivitty, so it doesn't work with anisotropic media.
