I'm really confused by the statement "We do not like save-update feature". What is there not to like? it's how you get the functionality you desire from NH. Otherwise it sounds like the naive mindset of using 3rd party tools ... I want your tool to work my way.... NH is extremely flexible, but it isn't magic. It can only knows what to do because you told it. you tell it through the mappings.
