You could create a template (.dot) in which you store the AutoTexts.
Distribute the template to the users as an add-in. If the template is stored
in the Word Startup folder, it will automatically be loaded as an add-in each
time Word is opened. AutoTexts (plus toolbars and macros) in all loaded
add-ins are available to all documents. Currently loaded add-ins are listed
and have a checkmark in Tools > Templates and Add-Ins.
When changes are needed, prepare a new copy of the template including the
changes. It is possible to have the updated version distributed automatically
if you wish.
For more details about the Word Startup folder and how to distribute
add-ins, see this article:
