The thread you linked is actually where all annotation feature requests should be made. They are all being directed to this catch-all topic.
I’m leaving this topic open for now, since the original question was about how to apply existing annotations, instead of suggesting new ones. But will close once that seems to have run its course, as the OP has already suggested.
Meanwhile please direct suggestions for new or different annotations to the linked topic, otherwise they may not get noticed by staff in this topic.
