CLONE - Session Qualifier or some other field

I want to identify each session uniquely through my own Id (not version, sender or target_comp_id combination)

I mean onCreate gives a callback with SessionId, which gives a combination of version, sender_comp_id and target_compid. sessionQualifier helped in giving my own Id, but SessionQualifier is not supported with acceptor sessions, Is there some easy way I can identify the sessions with the my own id?
