I'm looking for a way to surface the user that filled in an Actual Completion date.
Use Case 1: For many of our tasks, we have several assignees assigned to a task and would like to know which one completed the task.
Use Case 2: We have users shared into projects with Manage access who are marking tasks complete that they are not assigned to.
I've tried reporting on this but haven't found any field to even create a custom column off of. Has anyone tried to do this?
