Add custom post related by custom field to custom post

I hope to be able to explain my question.

My scenario is the following.

I have events post type created by a plugin for exhibition in a theatre season.

I want to have at the bottom of every single event a short bio of author(s), actor(s), … who have to be all in the same set as sometime actors are also director and viceversa.

I created by Pods a Custom Post Type people where I store bio, short bio, featured image and events (linked to events post)

I created by Advanced Custom Field three Custom Fields: director, author and actor as relation with people.

While I was able to create by pod template the post, for people in my "people template" I couldn’t.

In my event I often have more people for the same position.

By php snippet I could dump the multidimensional array of the director and i had my value, but after that I couldn’t go on.

Is there any plugin to do this.
Or there is any code workaround?
