Is it possible to combine rowGroup and row.child?

I have a table that makes use of row.child where each row is expandable/collapse-able, but my parent rows can and will have duplicate data. Is it possible to rowGroup the multiple duplicate parent rows and still maintain the expandable/collapse-able functionality from row().child?

The following is what I've tried, but it doesn't provide the expected results:

function loadDataTable(data) {
    var table = $('#List').DataTable({
        "data": data,
        "columns": [
            {
                "className": 'details-control',
                "orderable": false,
                "defaultContent": ''
            },
            { "data": "SomeVal1" },
            { "data": "SomeVal2" },
            { "data": "SomeVal3" },
            { "data": "SomeVal4" },
            { "data": "SomeVal5" },
            { "data": "SomeVal6" },
            { "data": "SomeVal7" }


        ],
        "rowGroup": {
            dataSrc: 'SomeVal1'
        },
        "order": [[1, 'asc']]
    });

    $('#List tbody').on('click', 'td.details-control', function () {
        var tr = $(this).closest('tr');
        var row = table.row(tr);

        if (row.child.isShown()) {
            // This row is already open - close it
            row.child.hide();
            tr.removeClass('shown');
        }
        else {
            // Open this row
            row.child(format(row.data())).show();
            tr.addClass('shown');
        }
    });

};
