Upcoming Events: Separate List for Last Minute and Next Events

At the moment it is not possible to separate Next Events (Begin is in the future) and Last Minute Events (Beginning is in the past but the cut off date is in the future) in the upcoming events module.

To achieve a nexte events list I modified mod_eb_events.php. By the way: Is it possible to create an override for core files of modules (not templates)?

Core EB file override is possible in some cases. See eventbookingdoc.joomservices.com/develop...stomization-override .
It usually works for me, but I recall coming across one file that I needed to mod that I couldn't override (I don't recall which file).
