Supergroup Admin job is very tough No clear history option is available to Supergroup admins . At least Select all option should be given while making selection for deletion/forwarding. That will help the admin to manage content in short span of time. Moreover its very difficult to delete old messeges one by one. Please show some mercy on admins. We are not able to rollback a well formed super group to normal so please consider it.
