I want to be able to define which mathematical formula I want to use on a cell in a pivot table. Some cells I may want to add other I may want to do an average.
Thank you for your idea. Currently you can perform calculations across rows/columns in pivot tables. Additionally, we recently introduced the ability to export pivot tables to Excel for advanced analysis. If you need to create unique calculations for some cells, exporting would provide a good workaround.
At this time we do not have plans to make updates to allow cell-by-cell calculations in pivot tables. We hope you understand.
