[keycloak-user] Global "reporting" role like admin but with read-only access to everything?

According to https://www.keycloak.org/docs/latest/server_admin/index.html#global-roles there are two global roles, admin and create-realm, but we would like to add a third one, call it reporting, that has read-only access to all settings in every realm (so all of the view- and query- permissions). We can create the role as a composite with permissions over every realm, but if a new realm is added later, the reporting role has no access unless we explicitly grant it. Is it possible for us to add a global role by creating a new realm role in the master realm, and giving it a particular configuration and/or set of permissions? Thanks! Regards, Peter K. Boucher
