Buy A or B or C Get D free Promotion Scenario with Quantity Break

Hi Everyone,

I'd like some help to define a promotional goods type modifier in Advanced Pricing for the following scenario.

Scenario :
Qualifying Items A or B or C
Benefit : If net ordered qty for above qualifying product is between 100 – 199, then get 3 qty of D free.
else If net ordered qty for above qualifying product is between 200 – 299, then get 6 qty of D free.
else If net ordered qty for above qualifying product is between 300 – 399, then get 9 qty of D free.
else If net ordered qty for above qualifying product is between 400 – 499, then get 12 qty of D free.
else If net ordered qty for above qualifying product is between 500 – 999, then get 15 qty of D free.
