few "beforeUpdate" callbacks(or any other callbacks) for one model

I need a few "beforeUpdate" callback for one model because they encapsulate logics which relates with different things.
And I want code to be readable.

Look at the model callback implementation in the codebase, likely in a file like lib/model.js or similar. Understand how a single beforeUpdate callback is currently registered and triggered. Research how to allow multiple callbacks for the same event, ensuring they execute in a defined order. Check existing tests for callbacks to see the expected behavior.
