Is there a way in Simulink/System Composer to override the drag and drop event?

I wish to drag a block from a different application and drop it into simulink/System Composer. Upon dropping the block, Simulink should call a pre-defined Matlab function.

Is this kind of drop-handler customization possible?

Yes, you can do it as an edit time check:
