DxaPropertyMarkup for managing lists of items in XPM

I have a list of Embedded Schema objects that I want to be able to reorder, add, and remove in the list in XPM.

I cannot find any examples of the correct DxaPropertyMarkup to be able to do this.

@if (item.calltoaction.Count > 0)
{
    <ul class="unstyled">
        @foreach (EmbeddedCallToAction calltoaction in item.calltoaction)
        {

            <li @Html.DxaPropertyMarkup(() => item.calltoaction)>
                <a class="@htmlClasses" href="@link" target="@target" title="@title" @Html.DxaPropertyMarkup(() => calltoaction.externallink)>
                    <span @Html.DxaPropertyMarkup(() => calltoaction.label)>@label</span>

                </a>
            </li>
        }
    </ul>
}
