word course - Can you lock a field so it does not update?

I wanted to know if it is possible to lock a field inserted into a Word document. We have a template which I do not have access to changing at my office. They have set the date up on automatic so when you create a new document based on the template the date always changes, even when you open the document 2 weeks later. Am I able to lock the date so that it remains on the date the document was created?
