How can I select the data type for the transfer function block in Simulink?

I want to have a Transfer Function with fixed-point data types in Simulink. The Transfer Function block does not allow me to select the data type.

This enhancement has been incorporated in Release 2009b (R2009b). For previous product releases, read below for any possible workarounds:

The ability to select the data type for the Transfer Function block is not available in Simulink.

As a workaround, the 'Digital Filter' block from the Signal Processing Blockset can be used which allows using data types other than double.
