Wow wow wow,
So my conclusion is correct, although some MVPs told me that I can't do it and there is no automatic method to do what I want.

I know this is not an easy task Mr. Guessed, hence you faced a problem because it's a dynamic field.
You are awesome, billion thanks Mr. Guessed, May God Protect you everywhere. I appreciate your help and time.
At least, it's Ok now.

Lastly, Mr. Guessed, what I do if I want to apply this VBA code to select range inside the document?

Again, million and billion thanks.
