Formula Calculations in Reports 2.0

Related products: CS Reports & Dashboards

It would be beneficial for Reports 2.0 to have simple formula calculations available such as +, -, SUM, AVG, %.  An Example where this would be helpful is with Email Logs.  We have sent a survey and within Reports we currently can't report on the "Outstanding" surveys.  If we could create a report with a formula that allows us to subtract completed from sent we would be able to get this data.
