Where should I add module dependencies for ng-sortable in mean.js

Question

I have this problem: where should I add module dependencies in mean.js (for ng-sortable)

One answer to this question was to add this code-line in the config.js file:

var applicationModuleVendorDependencies = ['ngResource', 'ngAnimate',
'ui.router', 'ui.bootstrap', 'ui.utils', 'ui.sortable'];

The problem is that I don't have a config.js file. Instead I have a config.json file. My question is how I could do the corresponding action in my config.json?
