I wonder if this meets your requirements. The font size in the picture is number two, but it is no problem to change it to number four.

Process: Adjust the number font size and superscript, select circled characters to reduce the text, and then use circled characters to reduce the text again.

The key is to use the circled characters twice, the first time it is misplaced, and the second time it is no problem. Don't ask me why, you have to ask Microsoft about this ~
