D365 is currently missing the capability to use Mix and Match discounts to be leveraged for BOGO scenarios that honor customer trade agreement pricing. With the current setup, a discount trade agreement is overridden by a mix and match discount line set to 0% or $0 off, meaning the customer is forced to pay full price for their "Buy one" item. It would be great for omni-channel and B2B customer mix if we could configure a BOGO retail promotion that honors the customer's pricing for the first item and overrides the price of the second. This could be as simple as a new type of discount group on the mix and match called "unchanged" or "customer pricing" that is treated as a required line that receives no change in pricing.
