Discount Requirement "Customer had previously purchased X" only works after order marked as delivered

Hi, quick question.  I have a discount set up with a requirement that a customer has to have purchased a specific other product before qualifying for the discount.  It works, but only after I go into the CMS tool and mark the order as delivered.  Is there a way to make it so that the discount takes effect immediately after checkout so that a customer can get the instant savings that we advertise?  I understand why it would be set up the way it is, so that the transaction can be completely finalized before offering the discount, but would still like to know if I have the ability to modify this behavior.  I so, where would I look to modify it -- the CMS tool, the source code, or the DB?

Thanks!

What discount requirement are you talking about?
1. Customer had spent x.xx amount?
2. Customer had previously purchased all of these product variants?
3. Customer had previously purchased one of these product variants?

For example, for "Customer had previously purchased all of these product variants" requirement follow the next steps:
1. Open \Plugins\Nop.Plugin.DiscountRules.PurchasedAllProducts\PurchasedAllProductsDiscountRequirementRule.cs file
2. Find

var purchasedProductVariants = _orderService.GetAllOrderProductVariants(0, request.Customer.Id, null, null, OrderStatus.Complete, null, null);

and replace it with

var purchasedProductVariants = _orderService.GetAllOrderProductVariants(0, request.Customer.Id, null, null, null, null, null);

Perfect!  Thankyou!
