Displaying product cost on draft order page

[Dean_Kara]

Hi everyone,

We process a number of order via phone/e-mail and, depending on the Customer, will sometimes apply different discount levels.  In order to do this more efficiently it would help if we could display the cost price of each product on the draft order page:

I assume that this would need to be done somewhere like customers/orders.liquid and update

</td>
<td data-label="{{ 'customer.order.sku' | t }}">{{ line_item.sku }}</td>
<td data-label="{{ 'customer.order.price' | t }}">{{ line_item.price | money }}</td>
<td data-label="{{ 'customer.order.quantity' | t }}">{{ line_item.quantity }}</td>
<td data-label="{{ 'customer.order.total' | t }}">{{ line_item.quantity | times: line_item.price | money }}</td>
</tr>

to something like:

</td>
<td data-label="{{ 'customer.order.sku' | t }}">{{ line_item.sku }}</td>
<td data-label="{{ 'customer.order.price' | t }}">{{ line_item.price | money }}</td>

<td data-label="{{ 'customer.order.cost' | t }}">{{ line_item.cost | money }}</td>
<td data-label="{{ 'customer.order.quantity' | t }}">{{ line_item.quantity }}</td>
<td data-label="{{ 'customer.order.total' | t }}">{{ line_item.quantity | times: line_item.price | money }}</td>
</tr>

Am I on the right track?

Thanks a million
