Scene Capture 2D, show a specific object? (not using post process)

I’ve added a scene capture 2D to my player via c++ and i was wondering is there a way for me to create custom show flags for example

SceneCapture->ShowFlags.CustomFlag = true;

or is there a way for me to show only a specific object. I did find a way to hide objects but its inefficient for my situation since i only want to show a single object.
I’ve been scouring the internet/forums and as soon as i get a lead it usually ends with no answer and the thread gets abandoned. Please help.
