no screen capture only want webcam

So, I've seen several two year old posts about people wanting different options for screen capture.  I see these options have not been added.  I'm having to use Articulate Replay to get what I want, and I don't want to have to go between two programs to get the look I want.  I want Camtasia to be able to capture webcam only, be able to switch the PIP position, and be able to separate the webcam and PIP channels.
