you could create the summary row by adding it to the dataprovider. there is an option to create a summary function.
you could monkey patch or create your own DefaultSummaryCalculator.as to have a diff summaryOperation. subtract the row like in the sum operation and count the rows like in the avg, so if more that two there is an error.
