Project Costing from Time Card - Consolidation

Content

When we run the import costs process in the projects module, a cost entry for each time entry (Calculated Time) is getting created, which makes a lot of entries even for a small population of employees. Moreover it will reveal the salary of the employee(based on the rate) to the projects user as they can see the employee details for each transaction and rate.

We are looking for a way where the consolidated job wise entries should be pushed to the projects. Is there any option available now to achieve the same.Please provide your thoughts. 

Thanks in advance.
