multiple cameras

Hi, I have a problem, just started with boinx. Always been mixing with traditional TVmixers, and then you are able to see what your filmphotografers are doin all the time in the monitors, during vinjetts and films in the program. I can´t find that kind of window in boinx, where you always can see the pictures from the cameras. Either you have to have the camera LIVE, or marked. It´s kind of difficult to plan the exact picture if you cant see it. What can I do? Do I have to have seperate monitors for the cameras?
