Customer support told me in the chat that the following is not possible. this makes the quote templates useless for me.
It would be convenient to have a code in the quote template that all the discounts are only shown on the quote in pdf of they are different from 0.00. Now it is only possible to show or not to show discount in the quote pdf. This way you either have no discount function in your quote, or the customer who doesn't get a discount will sure ask for it.
If there is already an option for this, please tell me how. Customer support couldn't.
otherwise I am sure it would be convenient for many companies!
