Yes, you can! You just need to visit the Quotations>Wholesale Tab page, select the request that you want to duplicate and click the Action Button.
You will see 2 different options:
Request with different information
Clone with the same information
Request with different information means that you will clone the same request and change some details, like the number of pieces, the variants chosen and also the destination (Shenzhen/Custom Address).
Clone with the same information means that you will duplicate the same request exactly as it is.
Just click on the option that you prefer and it is done! Easy right?
