My first thought was also time tracking. If you don’t want to use an add-on and you have a premium account you can use custom fields. I found @Kaitie’s post extremely helpful. I’d watch her video beginning at 25:00. Do you track your time? - #14 by Kaitie
My second thought was, if you can run an advanced search and save it you can set parameters such as: assigned to joe, created in the last 60 days, completed in the last 5 days. That would take a little evaluation on your part to determine the results but could be a workaround.
