Not really. The two sets of "preferred" routes (like Peter pointed out) are
due to altitude restrictions dictated by the traffic flow from the
KJFK/KLGA/KEWR trio. This is further driven by the runways in use. With the
possible departure/arrival combinations from the three airports, it would be
very hard to guess the preferred route of the moment. To put that into a
table would be confusing.

That being said, the routes from Long Island are pretty predictable going
west/southwest. Pretty much follows the preferred routes on the FAA
database.

This is one of the more brain-dead things the FAA does. There may be good
reasons why, from an internal FAA point of view, there are two sets of
routes. From a user perspective, however, it's absurd that they're not
folded into a single table.
