Feature Wish: Turn off "reflow" of text

When I read and annotate in books, I often like to draw brackets or otherwise note a section is important other than highlighting and underlining (which I do, as well).

But on the Kindle Scribe, I can't draw a bracket around a sentence; it gets placed a text box and the text reflows around it.

I wish we had the ability to turn it off so it would operate a bit more like an imported PDF.
