Highlighting linked objects in presentation mode

Hi All,

I have a wire diagram that is boxes with magnets and lines linking them. In presentation mode I’d like to be able to point at one box and have it highlight (which is does) as well as it’s connecting lines and objects that are connected to it. The idea is to show the flow of information cascading down the diagram.

Can this be done in OG, or does anyone have a recommendation for something that will work?
