When using custom searches such as the Include/Exclude search, the resulting contacts can be exported, but there's no option given to select the fields. Fields to be included in the export file are apparently predefined in the search. That might make sense in some cases, but we have a scenario where the export file is pretty useless. Working around this with a temporary group or tag is a hassle.
Why is it that field mappings are not provided here? And can anybody assess what it might take to alter that behaviour in core, or which follow-up problems that would possibly implicate?
