How can I wrap a long Path/Filename in a calc footer

I am trying to use the Path/Filename in the Centre area of a calc footer, but the Path/Filename is longer than the page width, and is truncated to the page width. I have inserted a couple of newlines after it so it does not overwrite the Left area and Right area text, but it is still truncated.

(Changing the text attributes to a smaller font from within the Header and Footer dialogue box doesn’t seem to make any difference, but that is not what I want to do anyway).
