How to use inheritance strategy TABLE_PER_CLASS in Jmix?

There is no example or some explanation but spring boot way do not work: Jmix always create foreign key to parent table where no data records.
For example next Spring Boot entities works: I can set any organization for user (small or big). Jmix with same JmixEntities produce foreignh key exception. How to do the same in Jmix ?

@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
@Getter
@Setter
public class Organization {

	@Id
	@GeneratedValue
	private Long id;
	@Column
	private String name;
}

@Entity
public class SmallOrganization extends Organization{
}

@Entity
public class BigOrganization extends Organization{
}

@Entity
@Getter
@Setter
public class User {

	@Id
	@GeneratedValue
	private Long id;
	
	@ManyToOne
	private Organization organization;
}

Hi,

Thank you for your request! We created an issue to improve studio behavior.

Now you can delete foreign key directly in database. If studio will suggest to add the constraint again, add this changelog to ignore list.
