Hi posterboy2020,
Thanks for joining us in the Intuit Community! I hope you're having a great week. I'm happy to go over the categorization options for QuickBooks Online with you.
Being able to categorize your expenses in finer detail is a great way to keep on top of your bookkeeping, including for travel expense transactions. While business transactions give you multiple options for adding categories, at this time, personal transactions can only be categorized as personal.
Here is an article that explains how to do so: Group products and services into different categories in QuickBooks Online
To help with making sure you have the information you need in your books, I recommend using the Notes section on a transaction to add these details. You can access this field by double-clicking a transaction that's been fed in from your bank feed. It should appear automatically when you select the Add transaction option.
You can share feedback about this feature and what you're looking for by selecting the Assistant feature your account. This will open up a chat window, where you can type "Feedback," hit enter or send, then proceed with the feedback options.
I hope this helps. Feel free to reach back out if you have any other questions.
