Hi,
When linked to the product in the order, there is no option to display it on the orders listing without coding something.
But if you're fine with attaching it to the order itself, then I have two propositions:
- you could create a custom field of the table "order". You'll be able to edit it in the "additional information" edit popup of the order, and you can display it as an extra column in the orders listing. The custom field will have many display settings so that you can display it on the backend order listing and make it editable in the popup while not display in the emails, the frontend, or the invoice.
- you could configure your order status in the System>Order statuses. There, you can add extra order statuses, and you can configure a color for each status. That color will be used on the order listing in the backend:

That way, you could simply change the order status of the orders based on what needs to happen and the color of the order on the listing will allow you to easily identify the orders you need to manually process.
