Time recording

i would like to see some method of grouping time spent on tasks please.
In our tech support office I want to record time spent on a number of specific tasks over the year.

Tasks would include Tech support, Training etc etc.
Each team member has their own version of each task.
Perhaps tasks could have an "include in time tracking" flag so that only those tagged as such would get included in cumulative reports.

Thanks - geoff
