Simulink callbacks when modifying model

Is there any callback available when user make change to the model? I need to know if there was change made within subsystem. Equivalent to DeleteChildFcn, but for any modification.

I know there are callbacks available in each blocks, but it requires all existing blocks ( and new blocks copied to model ) to have callback functions defined.

Open your model, File -> Model Properties -> Callbacks,

Any callback function that you can use? Maybe PreSaveFcn or CloseFcn to detect if the model is changed? get_param(Model,'Dirty')?

This won't tell me which subsystem has been modified. I need something like CreateChildFcn or MoveChildFcn. They are not available but I presume this is what Undo function utilize.

This kind of callbacks will be useful to dectect changes in subsystem. And we really need this similar function. Does anyone have sovle this isuue?
