Can mkgmap use is_in to filter out objects inside specific (multi)polygons?

 

In my case I´d like to unify ways inside cemeteries/grave-yards, e.g.
> highway=* & is_in:landuse=cemetery {set highway=path}

 

Check-styles isn´t complaining of the syntax, but the rule has no effect.

 

Similar has been discussed here, but without particular answer:

Thanks
