Apply discount not on first product

Hi ??
I would like to know if it possible to have a scenario like that:
Product A cost 30
If user buy 1 product A, total is 30
If user buy 2 product A, one product cost 30 and the second one have a discount and it’s 20 so total: 20 + 30 50
If user buy 3 product A, one product cost 30 and the second and third one have a discount and it’s 20 so total: 30 + 20 + 20

So the discount should apply only from the second product and not include the first one

I’m using Bulk discount with this settings:

But the discount it’s applied to all products when the user buy two or more of them, so if user buy 3 product A, the total it’s 20 + 20 + 20 instead should be 30 + 20 + 20.

Thank you in advance
