XMLC Include Files

Hi Guys,
 
Is there anyway to set/use property files with the server side include
files?
 
E.g.
 
Instead of hard coding
<!--#include
file="../../../eworksportal/src_mockups/xmlc/ReportPageFooter.ssi"--> 
 
Use something like this...
 
<!--#include file="${REPORT_PAGE_FOOTER}"--> 
 
???
 
Regards
KD
 
Ps.
Just want to avoid hard coding the path to the include files to make
maintenance easier later..
