Freestyle multi-linesets on one object?

Hi Blender artists–

I am posting for first time-- just trying to learn this amazingly elegant program after years of Lightwave frustration. The Freestyle module looks perfect for what I do-- linear geometric moving drawings.

I see how I can mark selected edges for the edge render and then control color etc. But is it possible to put different edges from the same object into different linesets so that I can make multi-colored objects? So far I don’t see how without splitting my objects apart.

Many thanks for any suggestions.
