Change Authorship/Delete Personal Information

Change Authorship/Delete Personal Information

I'd like to know if there is a feature to change the authorship of a zoho document, or when you save it in a different format like docx  (not just change who the owner of the document is).

I'd also like to know if there is a way to delete the personal information that may be attached to a document. Would appreciate being able to have documents that are anonymous/ don't contain my personal user information.
