US public companies and many other companies need to report on quarter to date amounts for each month of the quarter. An example might be for a company with a Jan-Dec fiscal year to report in February on the QTD profit and of this quarter (January + February) compared to the QTD profit and loss of last quarter (October + November). Because the periods covered attribute in column definition only has options for periodic or YTD, designing column layouts to provide this information can become extremely complex involving dozens of columns each with conditional print options when more than one QTD comparison in needed on the same report. A straightforward solution would be to add QTD in addition to Periodic and YTD as options available for the periods covered attribute of column definitions.
