    [balsheet-pnl] faster definition of balance lists
    
    because the accounts and accounts-cols-data have direct 1-to-1
    mapping, it is not necessary to map accounts and retrieve from
    accounts-cols-data. mapping from accounts-cols-data produces
    identical results, avoiding O(N^2) access from accounts-cols-data.
