Marking to identify when RN is present on slide

[ryanstraight]

Am loving integrating this into my Quarto decks! I wonder if there's a way to place a small identifier on the slide when notations are present on that slide. Perhaps a little dot in a corner, for example, that is one color when RNs are present on the slide and have not been activated, and have it change colors or disappear when all RNs have been triggered.

Thank you, again, for a wonderful Quarto addition!
