Default UI Menu: Architecture/Markers

Ribbon UI Menu:

Use drawing markers to add a shape with text inside. You can choose between a circle, square, diamond, and hexagon. These tools can also be found on the Drawing Markers toolbar. The marker is inserted with default text (1S, 2S, etc.).

You can edit the text on the General page of the marker's Properties. In addition, you can modify properties of either the shape or text by using the Selection Info palette.
