Matlab Code Generation, output file name option

I want to know is there any setting in code generation, which may generate the function name appended with some user string instead of the default ones.

e.g., as per my current model name is Integrated, and there are few integrated blocks (common_processing, core_processing etc.). When I generate code now, the files are generated based on the subsystem name.

Integrated_Env.cpp, Integrated_Env.h, Common_porcessing.cpp, Common_Processing.h etc.

If we want to append the name as Integrated_Env_V1.0.cpp, Integrated_Env_V1.0.h in the generated code itself.

But since th env is a Reference model, and multiple hirerachy I cannot set Treat as atomic subsytem as true.
