Column for subtraction of grand totals in pivot table - power query useful here?

[heretolearnexcel]

Hi,

I have a table of data that I turned into a pivot table. Here is an example of more or less the data I'm working with:
[TABLE="width: 1000"]
<tbody>[TR]
[TD]Date[/TD]
[TD]Type of movement[/TD]
[TD]Product A In
[/TD]
[TD]Product A Out[/TD]

[TD]Unit Cost[/TD]
[TD]Client[/TD]

[TD][/TD]
[TD]9[/TD]
[TD][/TD]
[TD][/TD]
[TD][/TD]
[TD]13[/TD]
[/TR]
</tbody>[/TABLE]

I turned the data into a pivot table and ended up with this:

[TABLE="width: 500"]
<tbody>[TR]
[TD]Type of movement[/TD]
[TD]Sum of Product A in[/TD]
[TD]Sum of product A out[/TD]
[/TR]
[TR]
[TD]B[/TD]
[TD][/TD]
[TD]10[/TD]
[/TR]
[TR]
[TD]A[/TD]
[TD]20[/TD]
[TD][/TD]
[/TR]
[TR]
[TD]B[/TD]
[TD][/TD]
[TD]9[/TD]
[/TR]
[TR]
[TD]B[/TD]
[TD][/TD]
[TD]12[/TD]
[/TR]
[TR]
[TD]A[/TD]
[TD]30[/TD]
[TD][/TD]
[/TR]
[TR]
[TD]A[/TD]
[TD]7[/TD]
[TD][/TD]
[/TR]
[TR]
[TD]A[/TD]
[TD]10[/TD]
[TD][/TD]
[/TR]
[TR]
[TD]Grand Total[/TD]
[TD]67[/TD]
[TD]31[/TD]
[/TR]
</tbody>[/TABLE]

I would like for the pivot table to display in the Grand Total row the difference between Sum of Product A in and Sum of Product A out, such that the result in the example would be =67-31= 36. I tried adding a formula next to the 31 which, supposing Type of movement= A1, would be in cell C9 and the 31 would be in D9. But if I filter for Type of movement and more values are added, changing the size of the pivot table, then the formula in D9 will no longer subtract the values from the grand total since they will no longer be in the original cells.

I tried using Power Query to changing the Type of movement column so that each unique row value of the column becomes a new column, and then I would be able to work the data to get the results I want, but I can't seem to find a way to do that in Power Query and keep all the corresponding data. The result I would like to get using Power Query would be something like this.

[TABLE="width: 823"]

Well... I just realized that wouldn't work for what I want. But still, is there any way to do that in Power Query? And regarding my original question, how could I achieve that with my pivot table?

Thank you in advance.

May I ask what steps you followed to achieve the result?
