How can I pick multiple images from the built-in picker Intent?

Question

Is it possible to reuse the picker Intent to select multiple pictures instead of one? I haven't found a way and I'm trying to reproduce it with a grid view but my alignment is very poor and my performance is not quite as good as the picker.

    Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
    photoPickerIntent.setType("image/*");
    startActivityForResult(photoPickerIntent, REQ_PICKER);
