To be able to include calculated fields & parameters to column headings. This functionality is possible for worksheet headings, it would be great if we could do the same for column headings too. The current workaround which involves placing a worksheet in front of the existing header (in fixed position) does not work in most occasions as the position of the headers may move due to a drill-down hierarchy or if the page uses dynamic sizing.
