Mongoose JS promises? Or how to manage batch save

How do I manage batch save in Mongoose? I saw it may not be possible yet:

• How can I save multiple documents concurrently in Mongoose/Node.js?

Theres some mention about using some flow control library like q, but I also notice there promises in mongoose, can it be used? Can I do like in jQuery Deferred/Promises

$.when(obj1.save(), obj2.save(), obj3.save()).then ->
    # do something?
