function called from view is showing as unused in PHPStorm

In my controller I have:

PHP Code:

public function save_info()
{
...
} 


This function is used in a view

PHP Code:

<?php echo form_open('config/save_info/', ['id' => 'info_config_form', 'enctype' => 'multipart/form-data', 'class' => 'form-horizontal']); ?>

I'm right in the middle of trying to convert this application to CI4. PHPStorm is reporting the function as being unused. Is there a way for me to reference the function in such a way that PHPStorm can see where it's being used? I've noticed in Controllers and models that as long as I am instantiating/including the class properly, it will pick it up, but I'm not sure how to do this for functions referenced in views.

I suspect that because it's used as a callback, that it's not possible, but figured I'd ask.
