Not really.  Thus far the best way I know to do this is something
along the lines of

   $PageFooterFmt = 'file:local/PageFooterFmt.php';

and then inside of PageFooterFmt.php you can do

   <?php echo $GLOBALS['ScriptUrl']; ?> 

or

   <?php echo FmtPageName('$ScriptUrl',$pagename); ?>

whenever you need access to those substitutions.

OTOH, I might explore creating a special 'fmt:local/PageFooterFmt.html'
feature that performs $-substitutions on the contents of the filename
that follows.  This might produce some unintended side effects, however.
In the meantime, you could always implement your own version of this
in local.php with something like:

   function PrintFile($pagename,$filename) {
     $filetext = file_get_contents($filename);          # PHP >= 4.3.0
     print FmtPageName($filetext,$pagename);
   }

   $PageFooterFmt = 'function:PrintFile local/PageFooterFmt.html';
