Default Sort Property for ManyArray

I have a proposal to include a functionality where we can provide the default sortProperty for a DS.ManyArray. In Most cases we end up using an extra computed property to achieve this. Here is an example use case

App.Commentable = DS.Model.extend

The above was my use case where I had to sort the comments on the created_at with the most latest being the first. It would have been good if I could do something likes this.

App.Commentable = DS.Model.extend

It seems that an ArrayController would be the best way to handle this:

App.CommentsController = Em.ArrayController.extend({
  sortProperties: ['createdAt']

Or if you donā€™t want to use an ArrayController then you can use Em.computed.sort


Thanks I guess the computed_sort method fits the bill perfectly.
