Live Cursor (outside of main)

I don't have the technical knowledge to develop something like this, but is there a way to have a live cursor (that is not your main mouse cursor) that can be window captured for live streaming. I stream Starcraft 2 (highly competitive real time strategy game) at a professional level to 2500+ viewers and would love if there were a way to show what I was looking at in real time on the screen, without it controlling my cursor.
