Events - multiple filters

I can't get multiple filters to work with perch_events_custom. Am I doing something wrong here?

Perch: 2.5.4, PHP: 5.5.3, MySQL: 5.5.33, with PDO Installed apps: content (2.5.4), assets (2.5.4), perch_events (1.9), perch_forms (1.7)

perch_events_custom (array(
             'template' => 'events/listing/custom-listing-day-grid.html',
             'sort'=>'eventDateTime',
             'sort-order'=>'ASC',
             'filter' => array (
                array (
                    'filter' => 'eventDateTime',
                    'match' => 'gte',
                    'value' => date('Y-m-d'),
                    ),
                   array (
                    'filter' => 'publish_on',
                    'match' => 'lte',
                    'value' => date('Y-m-d'),
                    ),
             )
            ));

If multiple filters isn't supported for events, how could I achieve this in another way? The author wants to be able to add events without publishing them immediately. Either one of these solutions would be ok for my client: 1. setting a publishing date in the future (that's what I've been trying), 2. to be able to save the event as a draft
