Hi there, @spjuneman.
Currently, we're unable to add multiple reference numbers on a UPS shipping label in QuickBooks Desktop (QBDT).
As a workaround, we can manually enter the second reference number in the invoice or estimate by customizing it. Here's how:
- Go to the Customers menu and select Create Invoices.
- Fill out the necessary information.
- Go to the Formatting tab and click Manage templates.
- Choose a template and click OK.
- Select Additional Customization.
- Check the box for Other and enter Reference No. 2.
- Click OK.
For now, I'd suggest submitting feedback to our product engineers. This way, they can review your suggestion and might consider including it in our future product updates. To submit a feature request, go to the Help menu and select Send Feedback Online. Click Product Suggestion and provide a brief description of your recommendation. Once done, please click Send Feedback.
Furthermore, you can check out this article: Set up and use QuickBooks Shipping Manager. It contains a detailed step-by-step guide on how we can process and manage your shipments using the Shipping Manager in QBDT.
