How to add new role one by one

[poozhan]

Hi
I need a rule
that if every product of a brand that I have selected totals $500, a 5% discount will be calculated
but PrestaShop calculates the sum of all products of that brand
I want to calculate each product separately to see if it is in this rule or not
Currently, if it selects 5 products from category X and the amount is $500, it calculates the percentage
I want each product in category X to calculate the discount if it is $500 and if it is less, it does not calculate that item
