Current version of JabRef does not allow to enter start and end dates of a conference paper in InProceedings eventdate (biblatex entity).
I can able to get these dates using
eventdate = {1992-02-19/1992-02-21},
within the editor, and it appears in the Eventdate under the Optional Fields 2 tab.
When I make changes to this entity from within the Eventdate under Optional Fields 2 tab, information is lost.
So, my requested feature is to be able to enter start and end dates of a conference in the InProceedings entity.
