如何复制工作表保护选项

我正在使用IXLWorksheet.CopyTo方法将工作表从一个工作簿复制到另一个工作簿，并且不复制保护选项。我认为这是设计出来的，但我需要复制它们。

private void CopyProtectionOptions(IXLSheetProtection source, IXLSheetProtection target)
{
    target.AutoFilter = source.AutoFilter;
    target.DeleteColumns = source.DeleteColumns;
    target.DeleteRows = source.DeleteRows;
    target.FormatCells = source.FormatCells;
    target.FormatColumns = source.FormatColumns;
    target.FormatRows = source.FormatRows;
    target.InsertColumns = source.InsertColumns;
    target.InsertHyperlinks = source.InsertHyperlinks;
    target.InsertRows = source.InsertRows;
    target.Objects = source.Objects;
    target.PivotTables = source.PivotTables;
    target.Scenarios = source.Scenarios;
    target.SelectLockedCells = source.SelectLockedCells;
    target.SelectUnlockedCells = source.SelectUnlockedCells;
}  

有没有比"手工"复制每个标志更好的方法？
