Hi Josh,
The annotation is associated with the selected data point. 3D Maps will automatically adjust the orientation of the annotation so it's always in a visible text size. It is not feasible to move them manually. Sorry for the inconvenience it has caused. We hope you could give feedback to Office about this need: How do I give feedback on Microsoft Office? You can try posting this Excel UserVoice. If more and more users vote the idea, it more likely to get the attention of the developing team.
Appreciate your understanding.
Regards,
Alex
