Multiple widgets

Hello, I have a widget comprised of an invalidation box and several other elements.

When I go to change the render opacity of the invalidation box, it looks like it’s changing the opacity of each element individually. You can see how the bright yellow (which is ProgressBar_HammerInt) is a different color when it overlaps with the element (ProgressBar_HammerFloat) underneath it.

Is there a way to render the entire element-hierarchy for this invalidation box in 1 pass, then change the opacity of that pass? (similar to what Nesting a clip would do in video editing software)
