Reprorting Customisation

Hi All,

I am pretty sure this is a feature request, but is there any way to add a calculated field to a report, which is calculated dynamically at runtime?

e.g. if i have fields (columns) A, B, C, which are integers, i want to be able to add a sum on the row, which would be a new field. That is i want the sum(A:C), not the sum of the column A.

Is this possible without exporting the data?

Thanks in advance
