I want to apply rebates to a group of items sold to a customer in any combination - is it possible in AX 2012

I need to apply rebate to a group of items. The catch is when the combination of the items reaches certain quantity, the rebate must trigger.

For e.g. I have to apply rebate when sales reaches 1000 Units of Item A, B & C in any combination. If I sell 200 units of Item A, 500 units of B, 300 units of C, then the AX should apply a rebate from the retro quantity 1.  Is it possible to achieve this via rebate item group or if Item code is selected as 'Selection' 

Thank you!
