Open issues for individual dialog filters
Copied from #6058:
1) All Area lists like (geoscope in classification or PolytomousKey) seem to handle "Add" and "Edit" differently which doesn't make sense.
2) I could not test if specimen.country still has Countries only as default. It seemed to be handled like all other Named Areas but maybe this was only due some presentings (I didn't want to delete all my preferences) here. Could you please double check?
