From relate field to relationship subpanel

Hi everyone! I have the next question and would be very happy if someone could help me : in my custom module “Schoold groups” i have relate field to module “Places”. Also i created one-to-many relationship between 'Places" and my custom field. And i need the next thing : when i go to certain place page i’d like to see all “School groups” that study at this place. I understand that i can just do relationships and do not use relate field, but is it possible to do it the way i want? How to transform information from field to subpanel? Thank you!
