Feature request: Discount on total amount
It would be quite useful to have a fixed amount discount for the total amount, in addition to the current per-item discount. For example: if someone is registering 5 people for an event, and they have a discount code for $50 off their registration amount, the $50 is deducted from the total amount rather than $50 off each ticket.
See this related question for another way this could work: https://github.com/civicrm/org.civicrm.module.cividiscount/issues/188
An organization we work with requested this, but it's not something we have funding to implement right now.
