Show Additional Entry Sorting When Viewing "Time Tracking > Timesheet"

I'm sending invoices for the previous month's hours and I'm wishing for "Last Week, Last Month, Last Quarter, Last Year" viewing options in addition to the current "This Week, This Month, This Quarter, This Year" viewing options.  Especially because I expect my clients and I to work together for indefinite periods of time.
