Registration with repeated fields, how to do?

Question

I have a register in the system that I am developing that will have repeated fields, I would like to get help in this implementation.

This screen is called Sequence which has the following fields

---

Date

Numero Sequencia

Lot

Name = Side A | Type | Camera

Name = Side B | Type | Camera

---

All the registration of Sequencia that will be carried out will always have Side A and Side B.

---

I created a class so that Views can see the classes corresponding to the register.

Class Sequenciaviewmodel

using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;

namespace GerenciamentoDeQuartos.Models
{
    public class SequenciaViewModel
    {
        public SequenciaViewModel()
        {
            Lado_A.Nome = "Lado A";
            Lado_B.Nome = "Lado B";
        }

        public Lote Lote { get; set; }
        public List<Lote> LoteList { get; set; }

        public Sequencia Sequencia { get; set; }
        public List<Sequencia> SequenciaList { get; set; }

        [Display(Name = "Tipo Lado A")]
        [Required(ErrorMessage = "O Campo {0} é requirido!")]
        [Range(1, double.MaxValue, ErrorMessage = "Selecione o {0} corretamente!")]
        public Lado Lado_A { get; set; }

        [Display(Name = "Tipo Lado B")]
        [Required(ErrorMessage = "O Campo {0} é requirido!")]
        [Range(1, double.MaxValue, ErrorMessage = "Selecione o {0} corretamente!")]
        public Lado Lado_B { get; set; }
        public List<Lado> LadoList { get; set; }

        [Display(Name = "Camara A")]
        [Required(ErrorMessage = "O Campo {0} é requirido!")]
        [Range(1, double.MaxValue, ErrorMessage = "Selecione o {0} corretamente!")]
        public Camara Camara_A { get; set; }

        [Display(Name = "Camara B")]
        [Required(ErrorMessage = "O Campo {0} é requirido!")]
        [Range(1, double.MaxValue, ErrorMessage = "Selecione o {0} corretamente!")]
        public Camara Camara_B { get; set; }
        public List<Camara> CamaraList { get; set; }
    }
}

Sequence Registration View ( Create )

    ViewBag.Title = "Create";
}
