Astonishingly easy, but formatting needs work. I did not copy exactly but found the part of the loop where the price is extracted:
{% assign final_price = nil %}
{% for item in order.line_items %}
{% if item.sku == line_item.sku %}
{% assign final_price = item.final_price %}
{% endif %}
{% endfor %}
{% if final_price %}
{{ final_price | money }}
{% endif %}
and pasted it, after backing up the original. A little formatting and this will be done.
I am betting that this method of pasting the code will work?
I take it back, I said that Shopify meant it could not be done easily. Wrong!
Thanks Brian!!!
