I actually did e-mail financial aid a formal request for review, explaining that some specific personal situations, and that the FAFSA is psychotic and clearly doesn't understand the cost of living in the Bay Area. They reviewed my letter and awarded me $7k in additional Perkins Loans and also $5k in FWS, which I originally didn't get -- even though I received it at the other schools to which I applied.
So, not a huuuuge amount but definitely a help! I would encourage you to reach out to them if you have a financial situation not captured on your FAFSA. This at least made me feel like HGSE wants me to be there, which I think might have been half of my frustration
