If you just want to use the same camera positions for multiple scenes and that’s the only property that is currently different, select the scene with the correct camera position and right click on the scene tab that needs updating. Choose Update. Alternatively you could make the correctly set scene active, select the scenes in the Scenes panel that need updating along with the active scene, click on the Update button and then deselect any properties you don’t want to change in Properties to update before updating.
Since the ability to control tag visibility in LO was added I find I don’t need to create multiple scenes for stacking. I can use copies of just one scene for stacking.
