Start and End Dates - BibLaTeX InProceedings

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.

This is a known issue related to https://github.com/JabRef/jabref/issues/2753 and https://github.com/JabRef/jabref/issues/3483.
