Shuttle service definition?

I'm working on a new construction project under the 2009 version and we recently received our preliminary review comments. We attempted option 2 of this credit, but were denied because the bus routes closest in proximity to the site are different directions of the same bus line (Line 52). The reviewer suggested we look into the recent Addenda that allows a shuttle service to a second bus line. There is an additional bus stop located well within 2 miles of the project site that connects to Line 52. Can we consider the public bus Line 52 as a shuttle that provides access to additional lines? The additional bus stop provides access to 3 different bus lines, which would allow us to meet the credit requirements.
