Unit Price & Net Price are fields that can not be changed on the line item/quote. I would like to suggest that we have the ability to change the name (keeping all other formats and calculations).
I need this also. The business I work for does not recognize Qty * Unit Price as Net Price. I am having to create custom fields and pre-calculate the values to pass into those fields to get the different "net" calculations, like Dead Net Price less Discounts.
