Hello, PBB22.
I can see how beneficial this would be for your business. Our Engineering team is constantly working to improve the product. I appreciate your help in bringing things like this to their attention. They take the time to review every request and try to collaborate them into the next available update for QuickBooks Online (QBO). I encourage you to send this suggestion to our developers through feedback. I also suggest visiting this site for future roll-outs/updates:https://feedback.qbo.intuit.com/
For now, Here's an article for more information: Customize email templates in QuickBooks.
I want to make sure your concerns are addressed. If there's anything else you need, just let me know. Have a great day!
