Hello there, wallymortar6970.
Thanks for posting your concern. I'd like this issue to be taken care of.
Being able to modify the business day time isn't possible in QuickBooks Desktop for it is set as default. While this option is not yet available, I'd appreciate if you'd let the Product Development Team know about this option. You can do this by sending them feedbackl. I'll make sure to do the same thing on my end.
Here's how:
- Choose the Help menu.
- Click Send Feedback Online.
- Select Product Suggestion.
- Enter your feature request.
- Click Send Feedback.
You can check for the latest features available in QuickBooks Desktop by following the steps provided below:
- Go to the Help menu.
- Click New Features.
- Click What's New.

Your feedback would be a great help for us to ensure that we improve QBO to help run your business better.
Please let me know if you have further questions about this or if you need help with something else, I'm always glad to help.
