Override insert and save methods

[mahdian888]

Hi there. Is there any way to override save and insert methods and replace these methods with my own customized version? (I saw this functionality in Mongoengine)

I know there is @before_event and @after_event decorator. but I actually want to customize the save method in such a way that, for example, wherever insert is called, link_rule has the specific value that I want.
