The Billing Report reporting group seems to allow every category, except by ticket or by client.
Has any one found a way to produce a report that show the amount of time worked on each ticket during a given week? I can produce a billing report that shows total time -- but if you open the ticket list, it does not filter the time based on the report (it shows total time on that ticket). I could use the category day of week (or most any field in the ticket), but not Ticket #. So I can't see how much time was spent on each ticket for a specifed period of time.
