Syncing with existing products on both WooCommerce and Etsy

Hello,

I’m looking for a plugin to synchronize my WooCommerce website and my Etsy shop.
The good reviews here make me hope I’m in the right place. ??
My activity is modest, I have less than 70 products in my shop (hand-made home decoration for babies, kids and grown-ups).

First question in my case is this:

I started selling on Etsy a few years back, and have my listings up-to-date there.
Then I created my own website, and exported my Etsy products to import them in WooCommerce.

Now I’d like them to be synced. Does your plugin allow to “link” existing products together?

I’m wondering if, otherwise, I’d risk having redundant products on one or the other platform when syncing.

Thank you very much.
