I've been looking through the Backbone documentation and sidecar/src, but I can't see a way this can be done.
We have a custom view with a tree/table view that combines multiple custom models and inline editing/calculation rollups. Dirty models are tracked, and then there's a method that iterates through all the dirty models calling model.save().
Is there any way to queue these up and use the bulk api to send those .save() requests?
