event_end_day or month for template

Hello

When an event duration is more than one day, I’d like to show the start date/month and the end date/month on the posterboard.

Unfortunately, the function ‘eventorganiser_posterboard_ajax_response()’ in event-organiser-posterboard.php does not retrieve the end date / month.

I’ve tried to add the following lines :
‘event_end_day’ => eo_get_the_end( ‘j’ ),
‘event_end_month’ => eo_get_the_end( ‘M’ ),
and it works, but if I change the php file, it will be erased if there is un update.

Would it be possible to add these 2lines in the next update ?
