Multiple selection with linked contacts field

Multiple selection with linked contacts field

Hello, In my contact module, I would like to add a "linked contacts" field, to be able to see in a contact card which other contacts this contact is linked to. And I would like to be able to select several contacts, not just one... I tried to create a "multiple selection search" field, but I can only add one contact.Is it possible to create a network of linked contacts between them, apart from their links via Accounts? Thank's !
