Wish: dialogs popping up at same monitor as my Rhino

Is it possible to have everything at the monitor in which I have my Rhino?

When I offer Rhino training, I show Rhino on a large second screen or beamer for the trainees. When I for example like to show the properties dialog or change a layer color, the dialog pops up at my laptop screen and I have to drag everything to the other screen.
The days after the training, when I work in the office again with my two screens, I have to drag everrything back to my primary screen.
