I have, `Transaction.has_many :splits` and Split has an amount:integer attribute. I'd like to ensure `transaction.splits = [split1, split2, ...]` the sum of split1.amount + split2.amount + ... == 0. It seems that :before_add deals with the splits one by one whereas what I'd like is to check the array that's being assigned (`[split1, ..]`) beforehand. Is such a thing possible?
