How to handle multi-date events as separate pages

The CMS Questions

I have events master pages that have multiple dates that are maintained via structured fields. Subpages for the events seemed too cumbersome to me.

However, it is now the case that each event should actually be its own page. The call should not be a problem with a custom route from slug and date.

However, I am having difficulties with the template overviews. At the moment I’m using a loop through the dates to create duplicates of the page and add the date as an object variable. Is there a better solution?

foreach($events as $event){

  $dates = $event->dates()->toStructure();

  foreach($dates as $date){

    $eventDate = $date->date()->toDate('Ymd');
    $eventTime = $date->time();
    $eventLocation = $date->location();
    $toDate = date( "Ymd" , strtotime("now +4 Weeks"));

    if($eventDate <= $toDate && $eventDate >= date("Ymd")){
      $eventClone = clone $event;
      $eventClone->eventDate = $eventDate;
      $eventClone->eventLocation = $eventLocation;
      $eventClone->eventTime = $eventTime;
      $sortedEvents[] = $eventClone;
    }
  }
}

usort($sortedEvents, function($a, $b) {
  return $a->eventDate <=> $b->eventDate;
});

That is very helpful. Is it possible that existing pages are always overwritten if the slug already exists? There should be several events, but I only ever have one:

$consolidatedEvents = new Pages();

        foreach($events as $event){
            $dates = $event->dates()->toStructure();

            foreach($dates as $date) {
                $eventDate = $date->date()->toDate('Y-m-d');
                $eventTime = $date->time();

                if($eventDate >= date("Y-m-d")) {
                    $event->setEventDate($eventDate);
                    $event->setEventTime($eventTime);
                    $consolidatedEvents->add($event);
                }
            }
        }

I have found a solution to the problem. This renews the slug.

$newEvent = $event->clone(['slug' => $newSlug]);
