changing a Close Date should create an entry in activity log

Whenever ‘Close Dates’ are changes it should be listed as an entry in the activity log for that specific deal.

Absolute no-brainer, U cannot quite believe this doesn’t imprint a simple log in the activity log, so can quickly and easily see in timeline when a close date was changed and by whom, and to what date.

How can this not exist? Beggars belief.
