Hi! I was wondering if anybody could tell me how I can bulk update all of the expiration dates on our site's coupon codes? My manager has a tendency to create custom codes for different customers, and now we have over 1500 codes that she wants to make sure will not expire, but they all have different expiration dates that are coming up soon. Is there a way to change all expiration dates to the same date in year 2020 or something? Thank you!
