This is something i had thought of as i read about Problems with annotate fingering... maybe the use of stamps instead a written annotation works better? As long you don't release the pen or Finger you could drag the annotation to the place you want... you could put your favorites into the floating command bar...and there is a magnifying Glas poppig up if you use your Finger, i was Not aware of until now... for better positioning
