Would it be possible have an option for tutors to resubmit videos for certifications that they are already certified in? E.g. if I am already certified in the pre-algebra course challenge, there would be an option to submit another certification video for it that would replace the current video on my transcript but I wouldn't get extra SP for it. I think that some of the certification videos on my transcript that I recorded a while ago aren't a very good representation of my current mathematical ability if I am to share my transcript to demonstrate my academic achievement to various organizations in the future even if I got a 90% or above.
