I’m not sure if this is the only way to do it, but I’ve modified computed properties in customizations like this (the example is using the `availableSorts` computed property):

```plaintext
 api.modifyClass('component:edit-category-settings', {
    availableSorts: Ember.computed(function() {
    let sorts = this._super();
    let voteSort = {};
    voteSort["name"] = "Votes";
    voteSort["value"] = "votes";
    sorts.push(voteSort);
    return sorts;
    })
  });

```
