Help for Aimeos

Hi my friends, I'm looking for help.

I want to modify the way in which the price of the products is "taken", the variants can be: quantity of the product, place, etc.
please guide me where to start or if aimeos has some functionality included for this type of functionality

Use the block pricing feature of Aimeos for the prices by adding several prices with a different minimum quantity each. For other variant dimensions, create a variant article for each unique variant combination and give them their own prices.
