Obsession 2 and ML marking

does anyone have a good marking trick for the Obsession 2? I've running two VL1100as and a few IQs and scrollers. A macro that would assist in back tracking to mark the MLs would make my next week go much faster. I know that you can update the focus group and that will fix any marking once cues are established but if there is any other way  Thoughts are helpful. Thanks.
