ember.js - Reuse a route in a different route

Question

I want to reuse a route inside a different route. Example:

App.Router.map(function() {
    this.resource('routeA', function() {
        this.resource('routeAA');
    });
    this.resource('routeB', function() {
        this.resource('routeA', function() {
            this.resource('routeAA');
        });
    });
});

This is not working because I think the first resource routeA gets overridden in routeB.

Is my speculation correct? Is there a better way to solve this?
