How can simulink coder/embedded coder generate multiple entry point functions?

Similar to matlab coder can specify multiple entry functions for C code generation at the same time, but how to generate multiple entry point functions/models in simulink coder and embeded coder? For example, I have the following 2 models, they have their own input and output, so how do I set it up to generate 2 model entry functions?

I have search some documents, it seems that simulink only supports single entry point function configuration, I can't find the relevant example reference
