The mailing list for listmasters using Sympa

[Amos <address@concealed>]

I know this can be achieved by simply using aliases, but since we were
asked, thought I'd see if this were an option.  Looked a bit in the
doc, but didn't find anything, so I think the answer is "no".  Anyway,
is there a way in Sympa to create a list that includes the members of
other lists?

Thanks
