I'm not sure I understand. I'm looking for a succinct way of expressing "this is nearly the same submission as this other one that already has a substantial discussion: you should likely comment over there". As I understand what you've said, nothing should be done as it's not an exact dupe? I don't see how that's helpful, as what would essentially be the same discussion would be potentially split across two (or more) submission threads. Or if you're saying it should be flagged [dupe] (as opposed to having a comment note that it's a dupe), I'm not sure I see much of a meaningful distinction between a [dupe] flag and a "dupe:" comment. I suspect I'm not interpreting what you've said correctly. Thanks for your patience :)
