Combine and hide invoice lines

Combine and hide invoice lines

In quickbooks we are able to create a invoice line that combines and hides invoices lines below.
eg.
Brochure design         $1000 (total of lines below, the client can see this line)
Graphic Design           $600 (hidden but entered to reporting and tracking purpose)
Account Services        $400 (hidden but entered to reporting and tracking purpose)

This is a function we use regularly in MYOB and Quickbooks and would be great to see in Zoho.

It helps with tracking and reporting but keeps the invoice simple and clear for client.
