Updating system fields via TM API

Hello everyone,

Quick question - has anyone of you ever updaded system fields via the TM API, such as changing the created by or changed by user field? I have found http://producthelp.sdl.com/SDK/TranslationMemoryApi/2017/html/bd9bfe10-d6f8-40f5-b1ad-e757938395cb.htm which shows how to update the Usage Count field but I was wondering if anyone has updated other system fields before.
