Pivot Table Row variance calc

Hi
Is there any way generating a calculated row e.g. Capacity vs Production Load variance in the example below?
50%20AM

Instead of sum, I want to subtract between above two rows.

Hi,

The only option to add something generated to a pivot table is derived properties. But, as far as I understand, that is not what you need. So, I’m afraid, that there is no generated rows functionality.
