Polymer Change Events on Sub-Property Changes

Polymer 1.0 supports binding to structured data using dot syntax as demonstrated below: 

<template>
  <div>{{user.manager.name}}</div>
</template>

In the above example, is there a way to get a <<property>>-changed event on the user property itself when any of it's sub-properties change? Right now, although the binding does update the sub-properties of user, my user-changed event listener only catches changes to the user property itself and does not catch changes to sub-properties.

Do I have to manually configure listeners for every single sub-property of the user element in order to listen to those events?

It looks like you have to define a listener for every sub-property, though there is a shorter way to do it, by defining an observers array: Observing sub-property changes
