I used the V4 mag poses in Poser6 and it adjusted the items.  The V4 readme file has a quick explanation.  If you have one V4 in your scene, use the V4 pose.  If you have more than one then you use the pose name that matches the figure name (i..e., V4_1 you use the 4_1 pose).  The magnet poses actually use cross-talk so you have to select the appropriate V4 figure you plan to wear the clothing before you load that clothing item.
