Want to create object which is not added in tree view and not selectable?

I have created circle using macro feature in solid works. I want to create display geometry(plus sign at the center of circle). I want to keep this display geometry along with created macro feature.

  1. I want this created display geometry should not be added in tree view.
  2. Display geometry is not selectable from view.

Is there any object in solid works which will satisfy this requirements?
