Change completion requirement without republishing? (many files)

Hi,

One of our clients found a slight snag with their LMS configuration. Their LMS (currently) prevents access to a course once it is marked as complete. Because our courses complete at 80%, that means that learners won’t see the remaining 20%.

I'm wondering if it’s possible to amend the completion criteria without republishing. We gave them A LOT of content, and republishing takes us a couple of full days of work. Is there something they can change in the manifest, or something like that?

Thanks for your help!
