I am running FP-Growth through Create Association Rules.

There is one item that occurs very frequently because it is simply very popular, and so produces a lot of spurious or "uninteresting" rules. Is there any way to specify an item should not be used, rather than inisitng that an item must be used?

But any more elegant solutions, or advice on more complex subsetting, still appreciated.
