Can I create a summary of hours by employee, then further break that employee's time by task hours? I can only find summary by task/reference and summary by employee. 

For Example:

John Doe PE                                                      

        Document Review     5.0 hrs     $500

        Project Management 5.0 Hrs     $500

 Jane Doe Esq

      Project Management   5.0 hrs      $500

Total Invoice                                      $1500

etc.. 

Thanks.
