AutoCAD Map 3D :: Styling Multiple Shp Files

I have a large batch of OS data covering the housing stock of a housing association which I'd like to break down into 81seperate local area maps. There are 162 of these files and each of the local area maps covers 3 or so of the shp files. I'd like to style each map the same.

So I go into the style manager for one of the loaded shape files and create a simple style.

rule 1 DESCGRP = "Road" Style: none
rule 2 Default = thin black polygon.

I'd like some way fo doing this automatically or simply. Because doing it 162 times with all the shp files loaded is majorly time consuming and at soem point I'd like to be able to use more complex styles. Is there any easy way of doing this?

I also have all the shp files as gz files if that would make life easier and as lines rather than polygons.
