How can I implement a price exchange for a price matrix?

Question

1C-Bitrix

A request was received to improve the functionality of the site, there is a catalog with goods, goods (not all) have a price matrix, example: A customer wants to set up an exchange of goods (prices) in order to update balances and prices, but the question is how can prices be updated in this matrix? On the 1C side, each product has 4 prices that correspond to the rows in the matrix, but it is not clear how to make it dynamically updated.
