Mapping of existing products in Woocommerce

Hello,

I just bought your plugin after asking the question on codecanyon :

“Is it possible to use your plugin only for automatic order placement via Aliexpress? Let me explain:

I don’t want to use the product import option (nor price synchronization and other options) but to map my products already present on my store that use custom attributes (for sizes, colors and options) in order to link them to products to be ordered on Aliexpress without having to alter my product descriptions, images and prices as well as the configuration of the products already existing?”

After installing and configuring plugin, I can’t find how to map my existing products and product variants in woocommerce to products and variants to be automatically ordered on aliexpress without modifying my Woocommerce products, could you please guide me?

Thank you in advance.
