Hi, I have a requirement to calculate internal costs against each product's line item - I would like to add this field as a column on the enhanced product view (see below) - but there is currently no functionality to edit this area.

Wouldn't allow me to attach an image, so here's the screenshot url

Without the additional field, it sort of makes this feature redundant, as the user would have to manually click into each line item to assign a cost and then save, click next item, etc (which seems very long-winded).
