How to specify grid width once in Bootstrap 3x (instead of once per media size)?

How to specify grid width once in Bootstrap 3x (instead of once per media
size)?

Twitter bootstrap 3.x changes the grid model so that you set grid cell
width and which media size to apply it to:
e.g. col-md-4, col-lg-12 (previously span4, span5)
Is there some short hand to specify the same cell size for any media size?
So I don't have to do this to get the item to be a 4 grid cell across all
media sizes:
<div class="col-xs-4 col-sm-4 col-md-4 col-lg-4">...</div>
