Materials overlapping

I want to make semi-transclusent selection circle for units (only circle with color and opacity, simple as possible) and I want them to render as one piece when they are overlapping.
On my screenshot, I want simply remove this overlapping effect marked with arrow.
All selection circles will be placed at one Z - coordinate
Is it possible to achieve it?

You can try using the “Scene Color” node and see if it has the effect you want.

Thanks, exactly what I need))
