Hi folks, how do we define a relation which is kinda global for all definitions. For Example, I want a specific group to be admin for all the resources created

definition user {}

definition group {
    relation member: user
}

definition organization {
    relation resource: resource
    relation admin: user
}

definition resource {
    relation admin: user | organization#admin | group#member
    relation viewer: user

    permission manage = admin + viewer
}
