Adding a PATCH method to Backbone collections - backbone.js

Question

I have a web application that is using a Django/Tastypie backend with a Backbone/Marionette frontend. I'd like to use Tastypie's bulk operations to create multiple objects via my API using a PATCH request to a list endpoint.
My understanding is that Backbone doesn't support this. What is the best way to add this to Backbone? I assume I'll need to add a save method to Backbone's collection object and extend the Backbone sync method.

From http://backbonejs.org/
If instead, you'd only like the changed attributes to be sent to the server, call
model.save(attrs, {patch: true}). You'll get an HTTP PATCH request to the server
with just the passed-in attributes.
Fiddle Sending patch request on backbone collection sync:
$(function() {
Backbone.$ = $;
var User = Backbone.Model.extend({
urlRoot: "/testUrl",
isNew : function () { return false; },
defaults: {
name: 'John Doe',
age: 25
}
});
var user1 = new User();
var user2 = new User();
var user3 = new User();
var user4 = new User();
var UserCollection = Backbone.Collection.extend({
model: User,
url: "/testUrl"
});
var userCollection = new UserCollection([ user1, user2, user3]);
// update
user1.set('name','Jane Doe');
user4.set('name','Another User');
// delete
userCollection.remove(user2);
// add
userCollection.add(user4);
userCollection.sync('patch', userCollection , { error: function () {
console.log(userCollection); } });
});
