QuickBooks remembers your last selection when reviewing bank feed transactions and will automatically pre-fill similar transactions with the same information. At the moment, there isn't a way to disable this feature, as it is a core piece of bank rules and other bank feed features.
That being said, we take feedback seriously here, as it helps us grow and improve. I can see how this would be beneficial in your case, so I'll forward this idea to our Product Development Team for possible implementation in a future update.
In the meantime, I recommend keeping an eye out on our blog for new features and news on everything QuickBooks. We post often there and showcase our newest features.
Let me know if you have any other questions. I'm only a reply away. Have a wonderful evening!
