Is it possible to globally set the filtering method for lightmaps?

Hi,

I know it’s possible to set texture options per lightmap via World Settings>Lightmass>Lightmaps, but I’m looking for a way to globally set the default options for generated lightmaps.

I’d like to disable mip-mapping and also change the filtering method. My goal is to achieved a stylised look using nearest neighbour, and tiny lightmap sizes which is why I don’t need mip-maps or even compression for that matter.

Any ideas would be much appreciated!
Thanks,
