The answer to your question is that yes this is possible to do this in a plugin, but this plugin doesn’t exist yet. Discourse core will probably not adopt this functionality (but I don’t speak for them) as Discourse is designed for discussions, not QA topics. Nevertheless, Discourse has a great plugin system.
If you’re interested in building this plugin yourself, I can help you figure this out. If not, post a paid job on the marketplace and there are a number of good developers who could take it (I don’t take paid gigs).
