File name to appear on score.

I have added the file name of my score to the footer, using $f.
During development this is very useful.
When I upload the file to musescore, the footer does not show this, only an internal code of some description. Fair enough, I realise that this might be the natural way that musescore.com operates.
I think that a similar thing happens to the header. The page numbers that are on my real score are not shown on the on-line score.
Is there some other way of adding these fields to my local score so that they are visible in the on-line score? I realise that this might be seen to be a musescore.com problem, but it is not really - I am not asking for any change to what musescore.com does.
Without this, keeping up to scratch with what version I've published is difficult.
and I can't see an easy way to embed fields like $f into anywhere else but the header or footer.
