I don't really have time to make it down to Union Station before my trip and I don't expect it to make a difference. The agent actually took down my info and called me back. Seemed that she had to check in with a bunch of different departments. She confirmed that kosher is an option with contemporary dining and a note was added to the manifest manually to add meals for me. It's just crazy that they switched to contemporary dining over a year ago and they still haven't ironed out how special meal requests work.
