Hi,
You can create an override for the HikaMarket vendor product listing and add the parameter "return_url" in the URL for the product copy.
The content for the parameter "return_url" should be url_encode and base64_encode.
But afterwards, if you want to redirect to the created product ; it would require some modification in the HikaMarket product controller but it would definitively require a modification of the HikaMarket import helper because the function copyProduct does not return the ID of the new product.
So, HikaMarket do not have any possibility to know what product has been created.
