Pivot Table - adding a column to total values per section

Summary

adding a column to sum values in each section

Content

We have a goal plan which is sectioned by goal categories. I am creating a report for our goal admins for this goal plan to have a quick and easy way to collect information for the goal details.

I have created a pivot table that shows the goal details of each goal within each category of this goal plan. Each goal has a weighting which is shown on the pivot table. To the left of the goal weighting for each category, I need to show the total (sum) weighting of the goals in each category. Attached is an example of what is needed.
