@GeneratedValue - how do I replace it with my function? (Java 8)

Question

Now the generator goes sequentially with step 1.

I need the ID to generate its own function.

How to substitute its function?

Thank you.

@Entity
@Table(name = "MovementHistory")
public class MovementHistory {
    @Id
    @SequenceGenerator(name="SEQ_GEN_MH", sequenceName="SEQ_MH", allocationSize = 1)
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator="SEQ_GEN_MH")
    private long id;
    private long waybillID;
    private Date dateEvent;
    @ManyToOne(fetch = FetchType.EAGER)
    private Status status;
}
