MATLAB: There is no sample time setting for HDL counter block

HDL Coderno_sampletime_counter

Hi,
I have done an implementation in sample down module, where I use HDL counter. But, the sample time in this block is cannot be configured due to which unnecessary delay registers are been assigned in the out put the code to match the down sampled.
No assignment
Unnecessary code (it is small part but it generate junck of this which is useless)
