Can you change an object in a blurprint in the editor viewport?

Is there a way to change a component via the editor viewport on a blueprint?

For instance I’m having someone help place enemies in the scene but he’s confused on what enemy is going where so I wanted to find out how to place icons next to the enemies in the viewport to show what direction the enemy is going. Basically

wanting to change the icon sprites . Is there a way to do this?

The image shows a green arrow pointing to the direction the enemy is going. I would like be able to change this icon on each enemy, is this possible?
