How do you set a clickable decal/icon for your blueprint?

I have a blueprint that is currently hard to select, but does what I need it to do. I figured I might be able to add an icon similar to how pointlights and refection captures work. The icon is just something to click on and doesn’t actually show up in the game or affect performance in any way.

Is this a MaterialBillboard I’m talking about? After some trial and error I tried that and it seems to do what I want. I made sure to turn off show in game.
