Insert at a specific location in Ember.Array Object

I know i can add new element to Ember.Array object by using

var ArrayObject.push({/*new element*/});

but, i want to know that is it possible to put an element at a particular location easily like

ArrayObject.insertAt(num,{/*new element*/}))

Note: i know the hard way by slicing(http://ift.tt/1qul3F3) and cancate(http://ift.tt/1IODdgr).
