Are you talking about Sketch Symbols? If you are, Sketch Symbols are similar to AutoCAD Blocks and you can add editable attributes.
First, start by creating a new IDW, next under the Drawing Resources, RMC on Sketch Symbols>Define New Symbol. Now design your symbol with your sketch tools (line, arc, circle…). Now to create an attribute, you will use the Text command. The Format Text dialog is present and there customize your text (Size, justification, color…). Look for the Type menu and change it to Prompt Entry. The text field area will display , you can change that text to something more descriptive.
Now you can hit the Return command to save and give the symbol a name. Now use your Symbol command on you Drawing Annotation Panel to insert that symbol into your IDW. Just like AutoCAD you will be prompted to add your text to each entry.
