Parts default file name change on pdf,.* export

Is there a way to change the default name of the file names, which MS saves for particular instrument out of the score (when doing export )?

for example:
I have a score with violin and piano ("old melody"), and I want to export the violin part, the file name will be now called "old melody-Violin.pdf".
Yet, I'd like to have a default file name like this "[Violin] $SCORE_NAME.pdf" or entirely generic (so that it works for all cases) "[$PART] $SCORE_NAME.pdf"
