Gender pay gap

We were told that we could report on the gender pay gap, however this isn't available anywhere in the system, could this be added to the highest/lowest earners report.

A query just gives us the background data, not the gender pay gap calculations and percentage.

Here's how you calculate the gap to report on; https://www.gov.uk/government/publications/gender-pay-gap-reporting-guidance-for-employers/making-your-calculations
