@Timothy Several people requested that syntax be added to enable conditional selection of field contents, such as when a first field is null. See the thread at https://forum.appcoll.com/topic/201/syntax-for-alternate-field-when-a-first-field-is-blank. I, for one, still would like to see such syntax added. For one thing, it would alleviate the need for one-off special fields, such as {Matter.ClientContact.NicknameOrFirst}, in that we users could program our own such fields.
