Conversion rate on emailed receipts

My recent work trip meant I used the receipt attachment and mail receipt function a hell of a lot more.

As a result it allowed me to claim back EXACTLY what i paid rather than what the expense system thinks I’ve paid with a conversion rate that does not benefit the user

What would be super useful is to show on the emailed receipt the rate at which the transaction was converted at so when I submit the expenses, payroll can see exactly what conversion rate I got at the time
