Federation addressbook sync not all users wanted on other side ;)

hi,

did i miss something or is it still not possible in NC26
or is it even me … overread another occ command
to exclude or better include (allow) contacts-system user (not addressbook) to get synced

i’m facing two NC in federation
NC-A and NC-B

NC-B just 2 users in contacts (will get some more soon)
NC-A about 15 in contacts (contacts is not addressbook)

i can not figure our why my users from NC-A show up in NC-B
at least not all of them should show up
only an elite circle would be the best way … so i added thme to a circle

so that on NC-B only these users out of 15 from NC-A show up
members of circle:
Maleficent
Cruella
Jadis
Yzma

And in an ideal world only the elite circle from NC-B show up in NC-A
members of circle:
Snow_White
Belle
Cinderella
Rapunzel

anyway to get this done ?

occ federation:sync-addressbooks

seems not the right way to get this done

thx for every hint
