Gift cards - multiple codes

Is there any workaround for a business owner to purchase multiple Gift Cards or gift codes in one go for their staff? Ultimately they just want the codes (say 10 or 100 at €50 each). So perhaps there is a customization option or a way for me to generate multiple codes for them, receive payment, and then release the codes? ... Or is the only solution to purchase one at a time!! 

Thanks.

For context ... from FAQs: 

Q/ Can customers buy multiple gift cards in one order? Or purchase a gift card with other products?

A/ No. When purchasing a gift card, customers go directly to checkout after clicking Purchase, similar to express checkout."

You can only purchase them one-at-a-time, as indicated in the FAQs. There isn't a workaround.
