Can I add a list of discount codes to a Typeform?

I know how to add a discount code by adding a “If = xyz @ price x 0.9” rule to the logic for example. But if I have 100 discount codes, is there no better way than clicking “If = a” OR “If = b” OR … 100 times? It also seems I would need to do it twice, since one logic rule governs the price variable and a different one governs jumping (I would like to show a different screen if they put a valid code).
