I appreciate you for getting back here in the thread, @IAS.

Before anything, I recognize the importance of having this feature work in your QuickBooks Online company. As I check here on my end, the feature you're trying to access in QuickBooks Online (QBO) is still unavailable. Please know that due to high volumes of feature suggestions. Our engineers might still haven't reviewed your feedback. With that said, I recommend resending a feature request to our Product Development Team. To begin, here's how:

1. Access your QuickBooks Online company.
2. On the top right corner, click the Gear icon.
3. Under Profile column, select Feedback.
4. Enter a brief description of your request, and then click Next.

Additionally, I've got you these articles to help you manage your invoices in QBO:

•  Customize invoices, estimates, and sales receipts in QuickBooks Online.
• Invoice customers for project expenses in QuickBooks Online.

@IAS, if you have any additional QuickBooks-related concerns or need help performing specific tasks in QuickBooks. Feel free to post here in the Community space. I'll be here, and I'll help you. Take care.
