[Boofo]

Yes, it can be done easily, if what you are wanting is what I understand it to be. As an example, here is what I did for that:

$templater = vB_Template::create('boofo_forumhome_event'); 
    $templater->register('callink', $callink); 
    $templater->register('daysevents', $daysevents); 
    $templater->register('eventdate', $eventdate); 
    $templater->register('eventdates', $eventdates); 
$upcomingevents .= $templater->render(); 

$vbulletin->templatecache['forumhome_event'] = $vbulletin->templatecache['boofo_forumhome_event'];
