Mailing list available to all admins

Hi!
Is it possible to add multiple owners to a mailing list?
We are an elementary school and I would like, as a superadmin, to prepare mailing lists for all teachers.
So different lists, for each class 1, available to all teachers.
Can I change something somewhere in the config to make this possible?
I don’t want to register all teachers as superadmin.
Thanks for an answer
