I think your only option is regular expression, but I don't think there 
is “nice” way to do it. You'll have to match on 3, 4, 5, etc. up to 
the maximum number of items in the identifiers. I'd love to be proven 
wrong though. Here is an example with levels 3 and 4:

	${list-id.identifier/([^.]+)\.([^.]+)\.([^.]+)\.([^.]+)|([^.]+)\.([^.]+)\.([^.]+)/${4:+$4.$3.$2.$1}${7:+$7.$6.$5}/}

It first tries to match 4 and then it tries to match 3.

I hope this helps.
