The usual trick is to overlap multiple pads, each with their own mask
geometries.  For example, you could have a normal pad for each edge
land, with a minimal mask setting, and a "dot" pad overlapping it with a
larger pad setting that just reaches the same spot around the segment
perimeter but overlaps between adjacent pads.
