Hello JasonGrant!

You can create bank rules in QuickBooks Online. Let me help you.

First, please know that the bank rule is designed to easily categorize the downloaded transactions. We're unable to use it to add a description but you can use the Memo field in the bank rule to add more details. Check this article on how to set it up: Set up bank rules to categorize online banking transactions in QuickBooks Online.

Also, you'll be the one to add conditions to the bank rules. When you select Description in setting up conditions, you'll need to enter keywords in the Enter text field which you think will be or not be the description on these transactions. These will be one of the bases how Quickbooks Online applies the rules.

In addition, the details showing when the transactions were downloaded are dependent on what the bank provided and this includes the description. If the bank continuously missed the other part of the description, you'll want to manually upload transactions into QuickBooks Online instead.

I added a link you can check: Categorize and match online bank transactions in QuickBooks Online. This will explain more about what to do with the downloaded bank entries.
