seems like it could be done, but it would be a potentially inefficient process. instead if just adding new identifications that would automatically withdraw previous ids, you would probably have to withdraw existing ids, then add the replacement ids, keeping the disagreement if the interim community taxon was the same as the taxon that was disagreed to in the original id.
i’m sure that this kind of process would not cover all cases, and i expect there would be some additional manual cleanup still needed at least some of the time. so i’m not sure how much of an improvement this might be.
probably the problem described in this thread could be addressed if the proposal in another thread was implemented: https://forum.inaturalist.org/t/eliminate-the-observation-level-can-the-community-taxon-be-improved-dqa-item-in-favor-of-an-id-level-cannot-be-improved-flag/26945.
