While tracing an area of continuous buildings in India, realized there was no easy way to create such a pattern of features in JOSM.

How does one split a group of ways using an intersecting line. The More Tools>Split Object command comes closes but works only with a single way and line that it encloses and is quite laborious.

Terracer plugin does not work well since the area is not a perfect rectangle, so it does not get the axis right. Any other editor/plugin capable of drawing this quickly?
