Your search/login particle is beautiful, I'd like to extend it a little bit like adding a "write blog" button and some other blog related buttons. And I want these buttons to be menu items in a "blog“ menu. Is it possible to add the custom position inside the particle to hold this menu? I understand bu editting .yaml and .twig files I can extend a particle, just want to know if I can apply a technique I just learned to particles, it is something like:

jimport('joomla.application.module.helper');
$modules = JModuleHelper::getModules('CUSTOMPOSITION');
foreach ($modules as $module){
echo JModuleHelper::renderModule($module);
}
?>
