symfony factory pass custom parameters for use after persist - ZenstruckFoundryBundle

EDIT

Forgot to include the package i am using: https://symfony.com/bundles/ZenstruckFoundryBundle/current/index.html

I am trying to figure out how i can pass extra data to the factory to use afer persist in some custom code.

I have a factory that generates a University, and after that is inserted in the database i need to then use the Course factory to assign courses which i want to do in afterPersist.

I have tried to add my own method to set the array of courses on the object:

/**     * @param array $courses     * @return $this     */    public function setCourses(array $courses) : self    {        $this->courses = $courses;        return $this;    }

And then call it like this:

foreach($this->universities as $university){            UniversityFactory::new()->setCourses($university['courses'])->create(['name'=>$university['name'],'slug'=>$university['slug']            ]);        }

However, i end up with an empty array in the afterPersists (this->courses is empty):

return $this->afterPersist(function(University $university){            foreach($this->courses as $type => $courseName){                CourseFactory::new()->create(['name'=>$courseName,'type'=>$type,'uni'=>$university                ]);            }        });

The array of courses does get assigned, but when running create() it gets emptied.
