There are really only 3 options here that I can think of:
     1) restore the entire job (probably to an temporary location), then 
prune the bits you don't want.
     2) use bscan of the volume to recreate the file list in the db 
(note that I have only used this when the job itself had been expired 
from the DB)
     3) restore a dump of the catalog that contains the file entries 
that you wanted that have been expired

I'm pretty sure I've done both #1 and #2, #3 I'd be much more reluctant 
to just try, as I would worry about clobbering more recent catalog data, 
unless you used a separate catalog db for the restoration.  Unless the 
job is really huge, I'd probably do #1, because bscan is (slightly) 
dodgy, especially for backups that span volumes (IMHO, note that it is 
_much_ better than not having bscan at all).  Sorry I can't provide more 
detail, hopefully someone else will be able to help more.
