Hi gormo,
Thank you for your feedback. You are correct. Based on initial feedback for this import we decided to tag each way created by our team instead of adding it to the changeset tags, mainly because of community requests. Having each way tagged also makes the process more transparent so the community can quickly give us detailed feedback if needed.
So you can find #nsroadimport #thailand for the changeset comment and source (source=*) = digitalglobe & import = yes on all our elements.
Best,
Alexandra
