Excel Pivot Chart Formatting

Hello everyone,

does anyone know, whether it's possible to format the data labels in Excel Pivot Charts uniformly to a different type at once? When I right-click at the (Pivot) bar chart and select "including/inserting data labels", all bars get data labels. However, when I want to change the type of label (e.g. value, title, etc.), not all bars get formated, but only one bar. Is there a quick solution that I can permanently change the type (from value to data row name) of all data labels? Maybe also for all data labels from data that will be added in the future? A "global" setting for this spreadsheet?

Thanks in advance for any hint!
