Making ghost features in Autodesk Inventor

I am trying to make a part that shows a cord connected to it, but I want that cord to basically be a ghost, so that it does not attach to another part.

For example, this hearing aid receiver has a cord on the end of it. When I make the file in CAD, I included the wire for orientation purposes, however this also slices up the part that it is digitally inserted into, in an undesired way.

Is there a way to make that part just there for illustrative purposes and not as a physical digital object?
