Open word document from one directory and set SaveAs in a diffent location

I am opening a Word template using the code below.
'file' contains the location and file name of the template.

MyWord = CreateObject("Word.Application")
MyWord.Visible = True
MyWord.Documents.Open(file)

I then fill the word document with the required data and the user either prints the document or saves it.
If he/she saves it, then default directory is where it was opened and it will overwrite the file as the name is still .dot.

How do I make it so that it is saved in a predifined directory with a .doc extension?

You could suggest copying & renaming the file to the required destination first, but if the user just wants to print the file you do not want it copied.

Thanks.
