[TYPO3-dev] PostInitializationModules on backend with requirejs

[elias]

I want to override the default option on DragUploader over the files ( i want to rename by default on the selector when there is a file with the same name on upload), so when i was looking for the best way to override:

typo3/sysext/backend/Resources/Public/Javascript/DragUploader.js

i have found that option:

$.each(TYPO3.settings.RequireJS.PostInitializationModules['TYPO3/CMS/Backend/DragUploader'], function(pos, moduleName) {
				require([moduleName]);
});


Seems that you could extends the behaviour of draguploader from there, but there is no documentation about how this must be done. Can someone explain how it could be done?.
