This should be done in modeler without any extra code and configuration

In a modularized application, the model and associated DataObjects are created once and then reused in many (possibly unexpected) scenarios

To stress this point, this is similar to why you'd have inheritance and composition in an OO language - you don't want all possible scenarios to be addressed in a single class (or file), with a long chain of if/else.

Configuration (model) reuse is facing the same problems.
