Sync products that were created before using AX Dropshipping plugin

I’m very satisfied with your plugin Aliexpress Dropshipping and Fulfillment for WooCommerce. For me just works perfectly. I would like to know if it is possible to upgrade the plugin with new feature to connect and sync products from Aliexpress that were created before using your plugin. I know I can do this manually and would like to ask which fields in database need creating/updating for everything to work correctly for the “old” products? Thank you
