Active Tasks in Timesheet in prior weeks

In timesheet view, when showing "Active tasks" in a given week, have it also include tasks that have been completed, but WERE active in the week being viewed (within the start and end dates of the task, and not cancelled).   The issue is when a task is completed on a Wednesday, for example, and I go to enter my time on a Friday, and have it show "active tasks", the tasks that were active that were but have been marked as complete no longer show.  For time tracking, my goal is to see all tasks that were active in that week, regardless if they have been since completed.  Helps with more efficient and accurate time tracking.
