Basically we want to import some documents from a legacy system into a vault and select a particular class where the value list will have several options. But going forward as others create new docs of this same class in the vault, we want to present fewer choices in the drop down. So both the imported legacy docs and new docs would be of the same class. And users could see the option selected in the value list for imported legacy docs. But they would not have all of those items in the value list when they create new docs. Is this possible?
