In order to keep the attributes ordered, useful and simple to navigate, it would be extremely useful to be able to mark attributes as only relevant to X constituent codes, so that that only limited numbers appear when navigating the drop-down. Like others on here we use the software not just for fundraising and it becomes a pain to fish through dozens or hundreds of attributes, many of which are only relevant to one constituent code. So if only a limited list were to appear once a constituent code had been entered we would be able to maintain much more information in a simple way without making the list too difficult to navigate.
