Grouping and spatially splitting up 3D models

I have a set of (thousands) 3D models in KML/Collada file. These represent a geospatial area.

I want to mass convert these into a set of OBJ files. This in itself is quite easy, thanks to the KML reader and the OBJ writer.

But now I need a way to split the big OBJ into smaller obj files, based on the spatial properties of the files.

I tried using the Tiler, but this doesn't seem to work for 3D objects. (Shame cause it felt like this is exactly what I would need)

I also tried using the Grouper in combination with the AttributeRangeFilter, but this would just amount to me having to create hundreds of OBJ writers to match the _group_index attribute written by the grouper. Which kind of defeats the purpose of trying to automate it.

So is there a way to output multiple Wavefront OBJ files instead of just one? And if so, how?
