One question, If I want to declare a moderator for all the sites,

definition moderator {
    relation moderator: user
}

definition site {
    relation moderator: moderator

    relation admin: user
    relation owner: user
    
    relation reader: user:* | user
    relation editor: user

    permission view = edit + reader
    permission edit = delete + editor
    permission delete = owner + admin + moderator
}

Do I have to manually add

site:x#moderator@moderator:bob

for every moderator for every site? How can I avoid this?
