Utilizing Overview panel to show some node and links only

GoJS
1

In my application all links are by default hidden by opacity. whichever node user selected based on that few links and Nodes gets full opacity and rest of the others opacity is reduced to 0.2.

In my overview panel, I want to show only the highlighted nodes and links (which have full opacity).
also if I can make it actionable it would be great.

I do not think that one can customize an Overview to be so discriminating in what it draws.

I was wondering if perhaps you could put all non-highlighted nodes and links into temporary layers, so that you could set Overview.drawsTemporaryLayers to false. But I do not know if that is possible in your app.
