Annotation Tool

Anyone know a way to make the annotation tool not "reset" everytime you change a screenshare? It always pops up on the lefthand side. I then move it to where I want it - at the top of my screen - and when I change my screenshare, it then will be on the left again. In the past, at least when I had already been to that document - the whiteboard, or a PDF, or a something I had shared before - it would pop back up in the same place as when I had left that type of document. As of this week, that is no longer happening. It just keeps popping up on the left side everytime I do change what I am sharing even if I've been to it before. Is there a setting I can choose to get it to show up where I want it to on every screenshare? That would be amazing if so, but I haven't found anything.
