Возможно ли в thymeleaf изменять id элемента при итерации?

<div class="list-group">
        <th:block th:each="c : ${List}">
            <a href="#myModal" class="list-group-item" data-toggle="modal">
                <span th:text="${c.name}"></span> <span class="badge" th:text="${c.listStudent.size()}"></span>
            </a>
            <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-hidden="true">
                <div class="modal-dialog" role="document">
                    <div class="modal-content">
                        <div class="modal-header">
                            <h5 class="modal-title" id="exampleModalLabel">Список студентов</h5>
                            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                                <span aria-hidden="true">&times;</span>
                            </button>
                        </div>
                        <th:block th:each="r : ${c.listStudent}">
                            <div class="modal-body" id="modal-body" th:text="${r.name}">
                            </div>
                        </th:block>

                        <div class="modal-footer">
                            <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
                        </div>
                    </div>
                </div>
            </div>
        </th:block>
    </div>
