Advanced Config
Advanced Config controls how Pricesystem compares the matrix result with other price types. Matrix assignment and matrix-to-matrix priority remain part of Product-Customer Matrix.
composer require mageb2b/pricesystem-advancedconfig:*
php bin/magento setup:upgrade
php bin/magento cache:flush
See Pricesystem Advanced Config for customer overrides, customer-group overrides and formulas. The matrix candidate uses product_customer_matrix in shared selection rules.
