... I was aware of the Bookmark trick and it's a
valid solution if your could lock them down to prevent deletion. If
you have any tips to prevent the deletion of these...please let me
know. ...

Instead of using a bookmark as the source of the repeated text, you could
use text values stored in
File Properties Custom
There, you can define name=value pairs like ProjectName=widget.

Then, for each repetition, you can use
Insert Field Document Information Doc Property
Also click Options and choose the property of interest; then click "Add to
field" and "OK".

(After the first time, you can copy and paste the field rather than going
through all the steps.)

The text value might be deleted if somebody deliberately goes into the file
properties, but it won't be deleted inadvertently by somebody editing the
document text.
