Show Cue System

There is probably a simple way to do this and I'm just missing it. I use SCS in a theatrical environment. I have used it for projections during performances with no problems. But I am using it on a new stage with a new projector. The projector was mounted to the ceiling and is controlled with a remote with limited functions. On install, it was initially focused on a descending screen at the apron of the stage; but I am projecting to the back wall. Right now, the image extends above the stage and on the proscenium sides. Is there a way I can re-define the output size of the 2nd screen so that it fits the dimensions of the projection surface on the back wall?
Thanks,

I haven't tried it but a simple way to do it might be:
In your cue file, with the projector running, in the Editor select the first image cue. Adjust the xPos, yPos, Aspect and Size (%) to fit the new screen. Select 'Other v' and 'Copy position, size and aspect into clipboard'. For each subsequent image file click 'Other' and 'Paste position, size and aspect from clipboard' for a quick way to repeat it.
