Simplify matrix using symbolic matrix

Hi guys,

I have a matrix like:

[1 0 0 0 0 0

0 1 0 0 0 0

0 0 2 0 0 0

0 0 0 2 0 0

0 0 0 0 1 0

0 0 0 0 0 1];

How can I represent the matrix in a symbolic way:

[X 0 0

0 2X 0

0 0 X];

where 0 here means 2x2 zero matrix, X means 2x2 identity matrix.

Thanks in advance
