How to recall a coupon created in previous email template

Hi
So I have created a secuence of emails to recover the cart, however in one of them I generate a coupon and in the next one I’m supposed to point out it is expiring soon by mentioning it again. How can I do that? There are only 2 options in the plugin: To use and existing coupon or to generate a new one, however want I need to do here is to recall the exact coupon dinamically created in the previous step. What should I do?
