Hi @Anonymous,
There are many ways to do this such as with a LISP routine, DIESEL code, and my favorite, using fields either by themselves or as attributes in a block.
I made a quick video that shows how I can insert a field and set it to a document property of Last Saved By. The same steps could be used to insert the date or even linked to custom Drawing Properties.
I hope this proves useful.
To put this in a block with an attribute, use the ATTDEF command with a Field

And then add the attribute to a block.
