Kerry Raymond suggested (https://lists.wikimedia.org/pipermail/libraries/2019-June/000819.html) that for campaigns like 1lib1ref we should integrate Hashtags stats with the dashboard campaign stats. Perhaps, we could have a feature to specify a hashtag for some event and pull the edits from hashtags tool via its API. (for example https://hashtags.wmflabs.org/json/?query=1Lib1Ref)
