Design Table control of part pattern skipped instance

I am using SW2008 with SP4

I read through the previous posts and could not find a definitive answer on this subject with respect to PART files.

I would like to drive which instance of a pattern is skipped from a design table. Can this be done directly?

I saw someone's suggested work around of creating a pattern for each skipped instance and then driving the suppression of the pattern. I was hoping to avoid that and drive the skipped pattern directly. Is there a syntax for addressing the skipped instance.

Thanks,
