Pay at pump, manual adjustment

Hi, would it be feasable to insert an option into the app where after you’ve used pay at pump, you can manually adjust the pre auth to the amount you actually spent?

So rather than waiting for the amount to change when the merchant takes payment for the money, you can ring fence the amount you spent manually yourself so you don’t accidently overspend.

Good idea or an alternative could be pay pre auth from pot a bit like the direct debit from pot, that’s a great feature.

It is a good idea, but this comes up at least once a month.

Here’s the same thing from Dec last year. There’s threads before this date too.
