[keycloak-user] No LDAP Group Attribute mapper in Keycloak?

Hi, If I am correct there is no LDAP Group Attribute mapper in Keycloak right? There is a User Attribute mapper and there is a Group Mapper but group attributes in LDAP cannot be synched to and from Keycloak at the moment? I guess it should not be too hard to write an LDAP Group Attribute mapper should we want to? cheers
