Modify the oData results grouping before binding to OVP Donut chart?

current-chart.pngto-be.pngI have a Donut card created for standard oData service SD_SOFI. Created local annotations and the card is rendering fine with various sections.

Now I need to show only 5 sections on the Donut chart containing top 4 sections and all the remaining sections grouped as 1, named Others. A total of 5 sections.

Can anyone suggest how to achieve this via OVP Cards or any extensions, please. I know this can be achieved if we create the complete card manually using VizFrame and call oData service manually and format data and bind it to card control. But I would like to know if it is feasible to achieve it via Overview page, annotations and extensions.

Thanks in advance for your help.

I believe you cannot manipulate the existing card using extensions, even if you do it somehow, it might cause issues in the upgrade. Only way is to extend the backend odata service to do it or like you mentioned, by using the custom card.
