How to generate Hierarchical C codes using Embedded coder?

I have created a Simulink model that has various simulation blocks. I want to create C codes for each block separately using Embedded Coder compatible with my Renesas controller to test them individually. But once I have unit tested them, I want to integrate them into a single model. The problem with Embedded coder is, it is treating each block as a separate Simulink model while creating the C code. As a result, I am facing duplication problems.

Make each block a model reference and in the generated code, each model reference block should have their own .h/c files.
