[OpenAFS] Problem for file system navigation in a backup volume tree

In our AFS space the user home consists on an AFS volume (located on a file 
server in the geographical site where the most relevant computational 
resources for the user are located) under which other user related AFS 
volumes in other geographical sites are also mounted.

When the user explores the content of the backup version of his main home 
volume the mounts points of his volumes on other sites lead him NOT to their 
backup version but to the related RW volumes and this is very confusing for 
the user.

This would be avoided if the navigation criteria for backup volumes were 
almost  analogous to the criteria for the navigation in RO volumes, that is 
AFS should automatically provide the access to the BK version if the mount 
point  is itself in a BK volume and a BK volume exists.

Would that be possible?

Are there other solutions for the problem?
