[MM3-users] Nested lists possible

There are two kind of members of an organization, general and inner ones. There is a list for the inner members and I don't want to duplicate their names in the general list.

I have already put the inner list as member of the general list and it works, however, the subject includes both prefixes and there are also both footers. So, the result is not really acceptable.

Are there any other possibilities?

Thank you in advance for your help.
