Encroached vias

How does one go about making encroached vias, such as ones that would be used on the dogbones under a BGA?  I know there is the global "over/under size pads by" in the plot options under the CAM setup for the soldermask layer.  I just want the vias under the BGA to have no/minimal opening vias to prevent bridging during soldering.
