Can I group "Product/Service" in the new Invoices? Previously I was able to group all the billable time for a specific service. I don't want to have a line item per time.

I am aware of the advantages for businesses like yours to be able to group Products/Services in the new invoice, @DigitalEventNomad. 

I want QuickBooks Online (QBO) to have this feature as much as you do. But QBO is still unable to show that way. However, I strongly urge you to share your thoughts with our software engineers. They carefully examine customer feedback, especially when determining how to improve QuickBooks.

Here's how:

1. Sign in to your QuickBooks Online account.
2. Go to the Gear icon and select Feedback.
3. Type in your suggestion and click Next.
