MATLAB: Can I modify how a native Simulink block is auto-coded

Question

My Simulink model uses native Simulink blocks within multiple atomic subsystems that are defined as reusable functions with unique file names. When I auto-code my model, the native Simulink blocks get auto-coded as in-lined functions within the atomic subsystem's auto-generated function file. The problem comes when another atomic subsystem also uses this same native Simulink block, but, this time, the MATLAB Coder placed just a function call out to the code that is now in-lined within the other atomic subsystem's reusable function. This creates a dependency between the two subsystems' functions and the order in which they are compiled. Is there a setting either on the native Simulink block or within the model code generation configuration parameters that will allow me to specifify exactly how I want the native Simulink blocks to be auto-coded. I would like to have them coded as reusable functions within their own uniqe files which can be called by my other code.

The Code Replacement Library seems to be what you are looking for. See this example:
