Business Reports older than 2 years

I have asked Amazon support and honestly don’t why I bother. After 5 years selling on Amazon, I still have hope that maybe one day, they may have a semi-educated answer to one of my queries…

I need historical data for business reports. I can only get data going back two years which is not helping me.

Can anyone help me understand where I can find this info for both US and UK seller accounts.

Many thanks
