Donors and prospects frequently express their institution-related Interests to our staff and subsequently get invited to events and/or receive mailings around those topics. Often times these interests change over a period of time. Currently in CRM 3.0, Start Date and End Date fields don't exist for Interest values on the Personal Info tab, so when a donor or prospect's Interest changes, the only option is to delete that Interest from the constituent record. This isn't sufficient because it eliminates the history, which is usually valuable to have. Start Dates and End Dates would be ideal in noting the duration of Interest.
