How to "push" changes to a set of models ?

We work in an organization with a number of models. Is there a programmatic way to push a change to the models when they are either opened or closed (which ever is easier) ? The change is modify the PostLoadFcn callback.

What we want to avoid doing is having a script (or manual) checkout the model, modify the model, and then re-check it in. Rather, we want a mechanism so that the next time someone opens the model, the desired changes are "pushed" to the model without the user necessarily even knowing that the change has occurred.

How about using component-based modeling and modular design?

Have you create your own custom library, so you can save all your models inside. Then when you change a block in your library it will change all the blocks link to this one.
