Clone model with nested relationships

I would like to make a week planner for an organisation. I would be recommended that the administrator can make a template weekplanner, duplicate it for a specific week and make some changes to it.

The weekplanner looks something like this:

On a database level

1. Schedule Table

Schedule_id Schedule_name

1. Workshop Table

Workshop_id Workshop_name (like bakery, garden) Schedule_id (relationship to the Schedule table)

The Schedule has many workshops, every workshop belongsTo a schedule

1. WorkshopSession table

WorkshopSession_id Date/day of week Teacher (related with teachers table)

1. A many to many relationship beween the WorkshopSession and the students table. The workshopSession hasMany students, the student hasMany workshops.

I would like to be able to clone a schedule (with all relationships, all the way down to the many to many relationship.

I'm quite new to this.

I know that cloning a model is easy, like this

$clone = $model->replicate();
$clone->push();

But how do I also make a database copy of the workshops related to the schedule, the sessions related to the workshops and the students in the many to many relationship with the session?

Thanks! 🙏
