Plot to File Default Filename

In R2013, the default file naming convention for plotting to a file (jpg, pdf, etc) was [your dwg's filename].pdf

This was ideal for me.

Since R2013 SP1 (including R2014, which I've just moved onto), it has changed to [your dwg's filename] [name of the sheet you're plotting].pdf - as in "DSMC-AS-L Model(1).pdf" instead of "DSMC-AS-L.pdf"

I don't like that at all. Having to manually change it every time is pretty obnoxious.

Is there an way to change this?
