[Zope] LocalFS and relative paths

LocalFS is a very useful product, thanks to Jonathan. I'm wondering if it's possible to specify a relative path in LocalFS, e.g. specifying 'images' as ID and 'projectXYZ/images/' as basepath would mount sth like '($INSTANCE_HOME)/var/LocalFS/projectXYZ/images'? This would simplify moving LocalFS-enabled sites from one machine to another that don't have the same directory structure if you like to keep your stuff under the Zope tree, rather than at fixed paths. Currently, I delete LocalFS objects and recreate them when I move a site. Ayhan PS: Make this question a feature request if not currently available.
