How to enable multiple users in the Assigned User?

Hi, is it possible to assign more than one user to the Assigned User field of an Entity? If yes, how can I enable this? Thanks in advance...

Hi emillod, when I edit a custom or a built-in entity, I don't see the Multiple Assigned Users or Collaborators check boxes. Is there another setting that I need to enable so that I may see these 2 options? Thanks
