Woocommerce Bulk Variations Stock Update

Hello, We need an import tool for our Woocommerce variations. Like stock, prices etc... The import file is a CSV like shown below Variation-SKU Stock price 45455 100 22.50 45466 152 22.50 ---------------------------------------------------- Sample CSV Variation-SKU,Stock,Price 45455,100,22.50 45466,152,22.50 ----------------------------------------------------- The tool must be able to select a CSV file.... Upload the file... Find te Variation-SKU (which is unique) and update te Stocks, Prices etc of this variation. We already use a Woocommerce import plugin --> Product CSV Import Suite wich can merge/update variations... But this plugin requires us to put the main SKU in the CSV file... this is not possible for us
