Export naming help

When premiere exports a sequence it names the file whatever you have the sequence named.  In the past, with previous version of premiere, if I wanted to name the file with an code for my playout system all I had to do was add a forward slash so the exporter knew only to name the file whatever came after the slash in the file name.  After premiere 5 I think we seemed to have lost that feature... or did the icon change to something else.  If anyone knows how to make happen what I'm describing that would be awesome.  It's not hard to rename a file with the code but it would save me several hours worth of work over the course of the year.
