I don't think it's a facility which Linux provides, but I have come
across this kind of sub-division of write access in the past.  One
system I used had RWUD permissions - for Read, Write, Update, Delete. 
Write access gave you permission to add stuff to a file, whilst Update
access gave you permission to affect existing contents.
