Model with multiple data dictionaries

I have a top level model which has two reference models namely a.slx and b.slx . Both have their own data dictionaries namely a.sldd and b.sldd. If I have same simulink enumeration defined in both data dictionaries, as both models use it but I am not able to run the model, since MATLAB says, it is defined twice. But I want to use it this way. Is there any way to override this issue? I have read that Model Workspace can be used to resolve this issue, but I would like to find solutions within data dictionary.

This is a safety mechanism in data dictionaries such that you can't accidentally modify one variable, but not the other. The best approach is to make sure your enumeration comes from a single source.

To do this, you can put the common global data (like that Enumeration) in a third dictionary "c.sldd" and reference it in both "a.sldd" and "b.sldd".

But it makes things complicated when different people are working within one Simulink project. Usually enumerations are included with .h file for code generation. When enumerations are defined different in different data dictionary I would expect a warning but not an error.
