If you mean set up list-b to have the same membership as list-a and
have the membership of list-b automatically track that of list-a, the
answer is no, but there are things you can do if you have access to
the command line tools.

For a one-off mailing, set up list-b, probably with the same
subject_prefix as list-a, and also advertised=No and
default_member_moderation=Yes so members can't post, especially if you
will keep the list. Then use bin/list_members to make a file of
list-a's members and bin/add_members to add them to list-b.

If you wish to keep list-b for a possible future mailing, next time use
bin/list_members to get list-a's members and bin/synch_members to
update list-b. Or, you could do the first mailing and then use
bin/remove_members to remove everyone from list-b to be sure no posts
leak through, and then bin/add_members to add them back the next time.

If you don't have access to the command line, you can script the web
interface to get the members of list-a and mass subscribe them to
list-b. See

sample script.
