Final Price minus Discount

[chaaya]

VirtueMart 2.024c
I need to display the "Final Price minus Discount", "Discount", and "Final Price" for each item. Unable to get "Final Price minus Discount". Good to see so many options to display all those different prices. Unfortunately "Final Price minus Discount" is not among them. Note that it is different than "Base Price + Tax".
To explain, here is what I have:
Added a new Tax and Calculation Rule that adds 20% to the base price as a profit margin. Tax is 10% as GST. Discount is 5% for a particular category. What the user should see is the "Base Price + 20% profit + 10% tax", then the "Discount", then the "Final Price."
I am sure I am not the only one who would like this functionality.

Cheers
