Hello konkle,
We currently don't have an option to change the way transactions are being coded, or stop QuickBooks from assigning them to the wrong account. However, you can edit the bank information before adding them. In the For Review tab, select a transaction and select the correct account in the Category field.
You can also use the Bank Rule feature. It allows you to automatically categorize transactions based on the rules you've set up. To learn more about it, please see this article: How to Set and Use Banking Rules For Downloaded Transactions.
Let us know if you need anything else.
