Advance Pricing - Free the lowest

Hello,

We are trying to set up a new rule for sales and we do not know if it is possible to do it.

I will explain with a sample:

If I sell 3 units (for 3 different items), I would like to change the lowest price to free.

Item 1: 100 $

Item 2: 130 $

Item 3: 90 $

Item 3 should change automatically to 0 $, because it is a special promotion.

Is it possible to do this?

Thanks in advance,

Luis
