I haven't figured out this section. Very confusing with the documentation not helping. It seems to me you'd have to have a rule that included multiple tax jurisdictions. You can use a range of zip codes (10000-11005 format) but only when you apply it to the entire US not to NY. Weird. I'm still trying to get it to work properly. One thing I'd warn though, is not to delete the original ones as I did, because they seem to have some features that are not available when you create new ones. That seems to be my problem now. Wish I could be of more assistance.
