Bulk adding ids to Coupons

Hi

We have the coupon feature on our woocommerce site. We wish to add all of our our splashbacks and upstands as a product for discounting with a coupon code. They are variations on a variable product. If I try to add the products as a condition I have to key in the variation id one by one. Is there a way to bulk add these?

Thank you

Nathan
