Hi,
it would be good if there is a WidgetZone in the view.
"Views/Shared/Components/OrderSummary/Default.cshtml"
This should be in the column below of ProductSeName.
<td class="product"> <a href="@Url.RouteUrl("Product", new {SeName = item.ProductSeName})" class="product-name">@item.ProductName</a>
You could then add additional information such as serial number or similar with a plug-in.
Best regards.
