Open issues for "Add distribution aggregation to set subtree menu"
copied from #8677
- disable rank fields in case aggregation should run only on the 1 selected taxon (and not on subtree)
- pre-select of areas if area level is defined
- use message() for aggregation mode
- source type selection per source mode
- switch order of source modes (first have sub/super area source mode) to have the same order as for aggregation mode
- rename "Export unpublished taxa" to "Aggregate unpublished taxa"
