Filter grouped events list

Hi,

I am trying to create a page that would allow users to view only the list of events they have created and/or enrolled in. I have no problem filtering by owner id to get the list of events that have been created by a specific user (the one browsing). That said, i am struggling to see how i could also output events that a specific user (the one currently browsing) has joined/booked/enrolled into.

<?php $user_ID = get_current_user_id(); ?> 

<?php

$args = apply_filters('em_content_events_args', $args);

if( get_option('dbem_css_evlist') ) echo "<div class='css-events-list'>";

echo EM_Events::output_grouped(array( 'limit'=>10, 'pagination'=>1, 'owner'=>$user_ID)); //note we're grabbing the content, not em_get_events_list_grouped function

if( get_option('dbem_css_evlist') ) echo "</div>";

Please let me know if there is an easy way to do that.

Best,
Yvan
