Systers Mailman has a 'dlist' (dynamic sublists) feature which may be
what you want. This is mentioned at
That post is old and the repo at <https://launchpad.net/systers>
mentioned therein is also old, but it still exists although the
documentation links in the post and the README files in the repo are all

We have been looking at dlists or something similar for Mailman 3, and
Systers also has done Mailman 3 work (see <https://github.com/systers>).

You may be able to port the changes from <https://launchpad.net/systers>
to more current Mailman, or perhaps contact Systers for more
information. It appears they are still using a Mailman 2.1.12 version
with their changes. I.e., see <http://systers.org/mailman/listinfo/>.
