I am using version 1.5.5e and would like to know how to locate a specific discount coupon in the admin.

It only list Active coupons and inactive coupons. It will not list all coupons for some reason and when pressed (all coupons) it defaults to active coupons which turns up blank. (Would this be a software issue)

I have over 11,000 coupon codes which is a total waste of time looking for a specific code as you only appear to be able to go through page by page. Has anyone done anything to improve how the discount coupons work?

I am at present having to delete one coupon (10,000 to go) at a time because you are unable to bulk delete unused coupons.
