Steering Wheel KPI

Hi all

Im trying to create the tesco steering wheel so i can edit it in excel (picture attached)Tesco.png

I have had no joy in finding a template and have created something myself, the problem is it requires alot of manual work as it is effectively 3 pie charts that i have to set the value to 10 on all segments to get equal sizes!

Any help would be great, ideally i want to --

Create the Tesco look with editable segments that dont change size. also i want to format the segments to change colour based on a -/+ value

Thanks
