Is it possible to customize the discussion information displayed?

[yihui]

Recently I migrated about 10K comments from my Disqus account to Giscus. One problem I encountered was that I couldn't post these comments to Github Discussions on behalf of the commenters using their Github accounts (of course this is impossible), so I posted them using my own account, and included the info about the original commenters in the comments. See the comment section at the bottom of this page for one example: https://yihui.org/en/about/

Since I do have the original commenter names and timestamps, I'd love to use these information in the comment thread. I wonder if it's possible to customize the commenter name and time for a comment. I've read the message events in the advanced usage at https://github.com/giscus/giscus/blob/main/ADVANCED-USAGE.md but honestly I don't understand what I could do with them, or if they could solve my problem. Thanks!
