Time exports per employee

Can we have a feature where we can run a "time entries report" for specific members of staff, or to filter their hours for specific clients of the ctime export report now? The report seems to show total time per client, but not showing per staff member.
It would be great to be able to break down the hours per employee/role so we can ascertain how many hours are adviser time/admin time etc for the year to show cost to serve per client
