Could you not just use a Multi/Sub-object material and assign different id's for each direction, then apply a UVW map for each id? Or detach the elements with matching directions to seperate objects and apply a UVW map for each object, then apply a single material to the whole thing. Or don't bother with UVW maps and use real-world coordinates, remembering to check generate mapping coordinates and real-world coordinates when creating your objects.
