Not directly, no. When all you have is the name of the list, you
don't know who any of the subscribers are. Once you've handed the
message off to the list (or sublist) itself, it knows who it's own
subscribers are, but doesn't know who any of the other subscribers
are for any of the other lists.
With some command-line tools to dump the complete set of all
subscribers from the selected sublists, then do a "sort -u" on those
addresses and then re-import those into another list, you could
achieve the same results. But this is not automatic, and would
depend on you regularly running some sort of a cron job.
