Hi Chris, thanks for taking the time to provide feedback. We're also glad you're finding the IOS Software Checker so useful. Cisco is absolutely committed to improving and/or expanding these kinds of tools-- keep an eye on the Cisco Security Portal for any future announcements. I'm sure you're already aware of this feature, but the IOS checker can accept and parse a .txt file with up to 50 releases. It's not version storage on CCO, but hopefully it helps speed up your analysis.
