Code for displaying total of individual discount in total template

Code for displaying total of individual discount in total template

Hi,

I would like to know how can I display the total of individual discounts added to the products to a Quote Temple? I can find the individual discount given on a product by using ${Quotes.Individual Discount} how can I find the total of all the individual discounts (there are multiple products)?

The ${Quotes.Discount} will only give me the discount I add to the total invoice value.

Also need to find the Sub-Total (total before individual-discount, grand total of multiple products before adding individual-discount)?
