New question:

I have a Word document with the style I like:
1.) Single space
2.) Font: Microsoft Sans Serif 11
3.) Borders: 0.5"

Now I have the footer set up with:
1.) File name
2.) Date, in this format . . . 12/16/20 9:38:38 AM
3.) Page number

My current question is:
I use this Word document as a template (there's nothing in it).
I grab a copy of it, and I'm ready-to-go.

I see that it gives the document the current date and time, when you open it.

. . . but, the file name is not dynamic
. . . it does not change, when you change the file name

. . . is there a way for it to update this itself?
. . . or does this have to be done manually?
