How to show discounts by line item on invoice?

[AbleMods]

I know discounts are shown on the invoice once the order is complete. But is it possible to show those discounts by line item instead of lumping them all into one single discount line at the bottom?

Often times customers want to see their discounted price per line item instead of just grouping all the discount monies into a single total at the bottom of the invoice.

I've looked through the OrderItem class and there doesn't seem to be anything to indicate a particular OrderItem record was or was not been discounted.

Suggestions? is this even possible post-checkout?

On Administration > Configure > Taxes > Settings page, Set Invoice Display: option to line item mode and it will show taxes in line item mode instead of putting all taxes together.

Have a look at ConLIb/ProductDiscountsDialog control how they are showing discounts for each product. This may help you to adjust UI by showing discounts specific to each product.
