[MM3-users] Required permissions for mass operations

Hi, I've Mailman 3.3.3 running with some mailing lists and it works great. Now I'm looking for a configuration option. I'd like to have some users with permission to

• moderate lists AND
• perform mass operations (add members, delete members) AND
• change settings for single members (execute actions in menu point "Users", "Members") It should be impossible to change other list or mailman settings for this users.

To give them the moderation permission is quite easy: I add the users to the moderators of the lists. But for the user management I've to add the users to the list owners and then is there no restriction anymore to change the full list configuration. What can I do? I link to a documentation for this would help as well, but I found nothing.

Thanks a lot for an answer Torsten
