Adding large # of promo codes to a promotion?

We are wanting to create a gift card promotion. We are producing 1000 individual gift cards with unique promo codes. Is there a way to make a promotion in Keap and add 1000 promo codes to that promotion without having to manually “add criteria” for each promo code?

In essence, it would be great if just like I could paste a list of codes into the Promo Code field, that I could also paste the same codes into the “add criteria” field for a promotion.

Or is there another way to approach this problem? Thanks for any guidance/help.
