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.
