See unbilled time in Project Profitability report

Hi

I'm wondering to see if there's a way to see unbilled time in the profitability report? I've tried to customize the setup for the profitability report with the advanced profitability report feature. But I couldn't choose the columns to sum from anything else than account or account type.
The help says that a third option for "time entry" should be available as "type" for coluns but it is not. Am I missing something? All features regarding job costing and time entries are enabled.

What I would like to happen is that all time that is unbilled but approved from Project managers should show in the report as well to have a full overview of expected costs and revenues for the projects. There is allready another report showing this, but I cannot add it to the Profitability report to have a total revenue amount for the project including expected revenue.
