Highlighted / Selected object line thickness?

Hello.

Is there a way to change the line thickness of selected and higlighted objects? I just switched to a darker theme and the problem is that the selected edges on a default white surface are too light.

I might change the color to something darker, but it would be even better if it was possible to also change the thickness of selected object lines.

AutoCAD has this by default. Would be nice if something like this was also possible with rhino
