Customized Subtotal in Pivot

Hi Team,
I have a couple of challenges for you.
1. I want to show subtotals and totals in a pivot table. The subtotals shown here were added via right click "add subtotals". For column 4,5,6 works fine but for columns 7 and 10 it doesn't. Is there a way I can create an object/measure to mimic the formula in N34 and in O34?
2. I have a Filter Return by type because the complete data has different return Types. So, the solution should considered that this selection will change.
Thanks.
