      In MongoDB 2.6 we can use $position modifier to specifies the location in the array during update of an array in a document. But I would like to insert in an array in a subdocument.

      // Document schema:
{  subdoc: {
    array: ['0', '1', '2', '5', '6'] } }

// The following update pushes the elements in the end of array..
db.collection.update(
   { _id: tsId },
   {$push: { 'subdoc.array': { $each:['3', '4'], $position:2 } }});

// So, the result is
{  subdoc: {
    array: ['0', '1', '2', '5', '6', '3', '4'] }}

// But I expect
{  subdoc: {
    array: ['0', '1', '2', '3', '4', '5', '6'] }}
