Pivot tables - Constant/Non changing row on refresh

[TS70363]

Hello,

I have a Pivot table which has "Week starting" date as rows, "categories" as columns and "sum of sales figures" on that day of that week under that category as Pivot summary.

Can I have a hardcoded/constant row on the top just below the categories with "Expected Sales for each category"?

Thanks
