Populating drop-down menu for related pod

Given two Advanced Custom Type pods, “locations” and “contacts”, I would like a locations form that show all of the locations fields, including “contact”, which shows all of the contacts. That I can do, and the “contact” drop-down shows that “name” field of the all of the contacts.

What I would like is for the drop-down to show the name, email, and phone for the contact and then submit the ID.

Does anyone know if that’s possible? Maybe there’s a hook I can tie into…
